In recreational mathematics, Maris–McGwire–Sosa pairs (MMS pairs, also MMS numbers) (sequence A045759 in the OEIS) are two consecutive natural numbers such that adding each number's digits (in base 10) to the digits of its prime factorization gives the same sum. Thus 61 → 6 + 1 (the sum of its digits) + 6 + 1 (since 61 is its prime factorization) and 62 → 6 + 2 (the sum of its digits) + 3 + 1 + 2 (since 31 × 2 is its prime factorization).
