第 21313 題：整數唯一質因數分解

原題與已知條件

完整bounded integer factorization與exact primality。操作=upf-canonical-factorization；資料={"n":246}。請依 exact_ordered_tuple_declared_by_interface 欄序回答。

• G001 — 完整bounded integer factorization與exact primality。操作=upf-canonical-factorization；資料={"n":246}。請依 exact_ordered_tuple_declared_by_interface 欄序回答。

定義與適用範圍

沿用原題明示的論域、假設與來源 MKO 定義。本題已完成第二對話數理與中英語義覆核，並由原始參數逐題獨立重算模型、答案與每個算術步驟；原題仍為 candidate。

• mko-unique-prime-factorization

逐步推導

source operation=upf-canonical-factorization;original snapshot and mathematics retained

explicit ordered source output fields=[n, prime_multiset, exponents, product, complete_factorization_certificate, certificate]

ORIGINAL positive integer absolute magnitude=246>1

initialize remaining=n,prime multiset empty;invariant product(extracted)*remaining=n;every smaller trial divisor has been exhausted

upf extract divisor2 occurrence0 := div(246, 2)

upf extract divisor2 occurrence0 = 123

next divisor=2;previous remaining=246;all smaller divisors exhausted

extracted multiplicity=1;next remaining=123;remaining modulo2=1;extracted multiset=[2]

upf extract divisor3 occurrence1 := div(123, 3)

upf extract divisor3 occurrence1 = 41

next divisor=3;previous remaining=123;all smaller divisors exhausted

extracted multiplicity=1;next remaining=41;remaining modulo3=2;extracted multiset=[2, 3]

next divisor=4;previous remaining=41;all smaller divisors exhausted

extracted multiplicity=0;next remaining=41;remaining modulo4=1;extracted multiset=[2, 3]

next divisor=5;previous remaining=41;all smaller divisors exhausted

extracted multiplicity=0;next remaining=41;remaining modulo5=1;extracted multiset=[2, 3]

next divisor=6;previous remaining=41;all smaller divisors exhausted

extracted multiplicity=0;next remaining=41;remaining modulo6=5;extracted multiset=[2, 3]

upf canonical complete product factor0 := mul(1, 2)

upf canonical complete product factor0 = 2

upf canonical complete product factor1 := mul(2, 3)

upf canonical complete product factor1 = 6

upf canonical complete product factor2 := mul(6, 41)

upf canonical complete product factor2 = 246

exhausted trial divisors below7;terminal remaining=41;d*d>remaining;ORIGINAL n=246

complete increasing prime multiset=[2, 3, 41];full product=246;a composite terminal remainder would have an already tested smaller divisor

ORIGINAL n=246;complete prime multiset=[2, 3, 41]

ALL [prime,exponent] rows=[[2, 1], [3, 1], [41, 1]];product=246;no multiplicities discarded
