13 is prime, so it's factors are 1 & 13. 15 = 1 * 3 * 5, so 1 is the only common factor.
hcf = 15 lcm = 3510 270 = 2 x 33 x 5 195 = 3 x 5 x 13 hcf = 3 x 5 = 15 lcm = 2 x 33 x 5 x 13 = 3510
The GCF is 13.
The GCF is 15.
hcf(5, 15) = 5 lcm(5, 15) = 15.
The GCF is 5.
The GCF is 15.
156: Hcf of 13 and 39= 13 13*12=156 =156
The GCF is 13.
The GCF is 3.
HCF of 78156 and 169 is 13
13 the HCF of 65, 156,169
HCF is the highest common factor of two or more numbers. HCF of 9 and 15 is 3.
