5040 ÷ 1000 = 5 r 40 1000 ÷ 40 = 25 r 0 ⇒ hcf of 5040 and 1000 is 40.
The GCF is 10.
The GCF is 10.
5 is the highest common factor of 10, 25 and 40.
The GCF is 4.

The HCF is 5
To work this out, you have to split the numbers into the product of their prime factors: 25 = 5x5 40 = 2x2x2x5 The next step is to identify any common factors. In this case, both numbers have a 5 as a prime factor. Thus the HCF of 25 and 40 is 5.
5040 ÷ 1000 = 5 r 40 1000 ÷ 40 = 25 r 0 ⇒ hcf of 5040 and 1000 is 40.
The HCF of 40 & 12 is... 4
The hcf of 45 and 40 is 5.
HCF(40, 63) = 1
The GCF is 25.
The GCF is 25.
The HCF of the numbers 40 and 44 is 4.
The HCF of 25 and 50 is... 25.
The HCF of the numbers 18 and 40 is 2.
