The HCF is 26
It is: 8
It is: 12
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
because its the highest number that divides into them all evenly. 91/7 is 13, 112/7 is 16, 49/7 is 7 So 13, 16 and 7 do not have anything else in common
HCF = 14
The GCF is 30.
HCF(210, 308) = 14.
The HCF of 112 and 63 is 7
The GCF is 42.
28
It is 16
It is: 16
It is 35
The answer is 21
It is: 14
It is: 30
