The HCF of 165 and 210 is 15. The LCM is 2310.
what is the HCF for 11 33 121
The first two are prime so their hcf, and that of all three numbers, is 1.
Divide numerator and denominator by their HCF eg 35/77: HCF is 7 so simplifies to 5/11.
The HCF is 7.
Prime factors of 210 are: 2, 3, 5 and 7 Prime factors of 385 are: 5,7 and 11 Common factors are: 5 and 7 and so 5*7 = 35 which is the hcf
The GCF is 11.
The GCF is 7.
