7 (7 x 19, 7 x 31)
HCF = 56 LCM = 8008 616 = 2^3 x 7 x 11 728 = 2^3 x 7 x 13 hcf = 2^3 x 7 = 56 lcm = 2^3 x 7 x 11 x 13 = 8008
35. 350 = 2 x 52 x 7 385 = 5 x 7 x 11 hcf = 5 x 7 = 35
The Highest Common Factor is 11
Two or more numbers are normally needed to find the HCF
Divide numerator and denominator by their HCF eg 35/77: HCF is 7 so simplifies to 5/11.
what is the HCF for 11 33 121
The GCF 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 HCF is 7.
The GCF is 11.
The GCF is 7.
