Two or more numbers are normally needed to find the HCF of them.
The HCF of 4 and 5 is 1.
5=5x1 35=5x7 HCF=5
The HCF is 5.
hcf(5, 15) = 5 lcm(5, 15) = 15.
The GCF is 1.
The GCF is 5.
5 and 10 lcm- 10 and hcf= 5
The GCF is 5.
The GCF is 5.
The GCF is 1.
The GCF is 1.
HCF is the highest common factor of two or more numbers. HCF of 25 and 40 is 5.
