The GCF is 8.
The GCF is 35.
30 -> 1,2,3,5,6,10,15,30 210 -> 1,2,3,5,6,7,10,14,15,21,30,35,42,70,105,210 700 -> 1,2,4,5,7,10,20.25,28,35,70,100,140,175,350,700 GCF is 10
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 GCF is 30.
HCF = 14
HCF(210, 308) = 14.
It is 49
The GCF is 42.
It is 35
The answer is 21
It is: 14
It is: 30
21
The GCF is 8.
The HCF/GCF of 385 and 210 is 35.
