It is 16
It is: 1 is their HCF
23 is a prime number, 36 is not a multiple of 23 so the HCF is 1.
First, express each number in terms of its prime factors. 32 = 2 x 2 x 2 x 2 x 2 = 25 56 = 2 x 2 x 2 x 7 = 23 x 7 The highest factor that both numbers have in common is 23 = 8 THE HCF of 32 and 56 is 8.
45. 180 = 22 x 32 x 5 225 = 32 x 52 hcf = 32 x 5 = 45
The GCF/HCF of 23 and 32 is 1.
The GCF is 1.
The GCF is 32.
The HCF/GCF of 506 and 1863 is 23.
