1,2,4,8,89,178,356,712
Greatest Common Factor
We found the factors 215,712 . The biggest common factor number is the GCF number.
So the greatest common factor 215,712 is 1.
Lets's calculate LCM of 2140,9418
2 | 2140, 9418 |
1070, 4709 |
∴ So the LCM of the given numbers is 2 x 1070 x 4709 = 10077260
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/10077260
Therefore, the GCF of Fractions 215/2140,712/9418 is 1/10077260
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 2140,9418 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(2140,9418) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(2140,9418) x common factors =2 x 1 = 2
LCM(2140,9418) = ( 2140 × 9418 ) / 2
LCM(2140,9418) = 20154520 / 2
LCM(2140,9418) = 10077260
