73 | 657, 1022 |
9, 14 |
∴ So the GCF of the given numbers is 73 = 73
Now, list down the factors of 657
:1,3,9,73,219,657
Now, list down the factors of 1022
:1,2,7,14,73,146,511,1022
Greatest Common Factor
We found the factors 657,1022 . The biggest common factor number is the GCF number.
So the greatest common factor 657,1022 is 73.
Lets's calculate LCM of 917,2991
Given numbers has no common factors except 1. So, there LCM is their product i.e 2742747
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 73/2742747
Therefore, the GCF of Fractions 657/917,1022/2991 is 73/2742747
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 917,2991 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(917,2991) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(917,2991) x common factors =1 x 1 = 1
LCM(917,2991) = ( 917 × 2991 ) / 1
LCM(917,2991) = 2742747 / 1
LCM(917,2991) = 2742747
