To find the HCF of two numbers you first have to express them as a product of their prime factors. In this case: 15 = 3x5 39 = 3x13 The next step is to identify any common prime factors. In this case, both numbers have 3 as a prime factor. Therefore the HCF of 15 and 39 is 3.
39
93% of 39= 93% * 39= 0.93 * 39= 36.27

156: Hcf of 13 and 39= 13 13*12=156 =156
The GCF of 39 and 93 is 3. 39 = 3 x 13, 93 = 3 x 31.
The HCF of 39 and 20 is 1
It is 13
It is 13
It is: 13
