To find the highest common factor of 338,688, we have to find the factors of both numbers and list the highest common factor.
The factors of 338 are 1, 2, 13, 26, 169, 338
The factors of 688 are 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
The HCF of 338,688 is 2.
Lets's calculate GCF of 338,688
2 | 338, 688 |
169, 344 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 338
:1,2,13,26,169,338
Now, list down the factors of 688
:1,2,4,8,16,43,86,172,344,688
Greatest Common Factor
We found the factors 338,688 . The biggest common factor number is the GCF number.
So the greatest common factor 338,688 is 2.
Lets's calculate LCM of 91,100
Given numbers has no common factors except 1. So, there LCM is their product i.e 9100
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/9100
Therefore, the GCF of Fractions 338/91,688/100 is 2/9100
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 91,100 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(91,100) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(91,100) x common factors =1 x 1 = 1
LCM(91,100) = ( 91 × 100 ) / 1
LCM(91,100) = 9100 / 1
LCM(91,100) = 9100
