Can 1 be a multiple?

Yes, every whole number is a multiple of 1. We say that b is a multiple of a when a*n = b (where n is a whole number). Since 1*b = b, for any number b, all numbers are multiples of 1. It sounds like you also want to double-check your understanding of the two words, ‘factor’ and ‘multiple’.
