Lets's calculate GCF of 979,638
11 | 979, 638 |
89, 58 |
∴ So the GCF of the given numbers is 11 = 11
Now, list down the factors of 979
:1,11,89,979
Now, list down the factors of 638
:1,2,11,22,29,58,319,638
Greatest Common Factor
We found the factors 979,638 . The biggest common factor number is the GCF number.
So the greatest common factor 979,638 is 11.
Lets's calculate LCM of 101,312
Given numbers has no common factors except 1. So, there LCM is their product i.e 31512
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/31512
Therefore, the GCF of Fractions 979/101,638/312 is 11/31512
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 101,312 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(101,312) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(101,312) x common factors =1 x 1 = 1
LCM(101,312) = ( 101 × 312 ) / 1
LCM(101,312) = 31512 / 1
LCM(101,312) = 31512
