What is the greatest common factor of 30 45 60 and 105?
30: 1, 2, 3, 5, 6, 10, 15, 30 45: 1, 3, 5, 9, 15, 45 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 105: 1, 3, 5, 7, 15, 21, 35 Therefore, the greatest common factor(GCF) of them is 15. gcf(304560 105) = 15 Found by prime factorisation: 304560 = 2^4 x 3^4 x 5 x 47 105 = 3 x 5 x 7 hcf = 3 x 5 = 15 However, I suspect that you asked for the gcf of 30,45,60 and 105 and the commas were stripped (as they cause problems with accessing questions across the internet - putting a space after the comma would have left the numbers readable), in which case: gcf(30, 45, 60, 105) = 15 Found by prime factorization: 30 = 2 x 3 x 5 45 = 3^2 x 5 60 = 2^2 x 3 x 5 105 = 3 x 5 x 7 hcf = 3 x 5 = 15 [Curiously the hcf is the same in both cases.)
