The GCF is 1.
It is 35
385 = 3.85 × 102
LCM(68, 102) = 204 HCF(68, 102) = 34
The HCF/GCF of 385 and 210 is 35.
35. 350 = 2 x 52 x 7 385 = 5 x 7 x 11 hcf = 5 x 7 = 35
102.013
3.85 × 102
You need at least two numbers to find a GCF.
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 highest common factor of the numbers 136 and 102 is 34.
The GCF is 6.
hcf(87, 102) = 3. factorization method: 87 = 3 x 29 102 = 2 x 3 x 17 hcf = 3
