No.
no 4 is not a factor of 15 because 4 times 3 is 12 and 4 times 5 is 20
The only common factor of 4, 8, and 15 is ' 1'.
15 is a factor of 60.The proof: 15 x 4=60(It is, of course, not a prime factor.)
They are 15*4 = 60 and 15+4 = 19
The Greatest Common Factor of 35 and 14 is 7.
15
The common factor of 4 and 15 is 1. They are coprime, as they share no factor other than 1.The factors of 4 and 1, 2, and 4.The factors of 15 are 1, 3, 5, and 15.
Because 4 doesn't divide into 15 evenly with no remainder.
The GCF of 4, 15, and 50 is 1.
The GCF of 4, 9, and 15 is 1.
The factors of 20 are 1, 2, 4, 5, 10, and 20No, 15 is not a factor of 20.
15 x 4 = 60
