Greatest Common Factor
We found the factors 60,28,44,72,633,23,87,149,38,64 . The biggest common factor number is the GCF number.
So the greatest common factor 60,28,44,72,633,23,87,149,38,64 is 1.
Lets's calculate LCM of 7,2,7,4,7,3,7,5,3,3
2 | 7, 2, 7, 4, 7, 3, 7, 5, 3, 3 |
3 | 7, 1, 7, 2, 7, 3, 7, 5, 3, 3 |
7 | 7, 1, 7, 2, 7, 1, 7, 5, 1, 1 |
1, 1, 1, 2, 1, 1, 1, 5, 1, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 1 x 1 x 2 x 1 x 1 x 1 x 5 x 1 x 1 = 420
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/420
Therefore, the GCF of Fractions 60/7,28/2,44/7,72/4,633/7,23/3,87/7,149/5,38/3,64/3 is 1/420
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 7,2,7,4,7,3,7,5,3,3 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(7,2,7,4,7,3,7,5,3,3) = 1
common factors(in case of two or more numbers have common factors) = 6174
GCF(7,2,7,4,7,3,7,5,3,3) x common factors =1 x 6174 = 6174
LCM(7,2,7,4,7,3,7,5,3,3) = ( 7 × 2 × 7 × 4 × 7 × 3 × 7 × 5 × 3 × 3 ) / 6174
LCM(7,2,7,4,7,3,7,5,3,3) = 2593080 / 6174
LCM(7,2,7,4,7,3,7,5,3,3) = 420
