We found the factors 56,56,882 . The biggest common factor number is the GCF number.
So the greatest common factor 56,56,882 is 14.
Lets's calculate LCM of 79,20,60
2 | 79, 20, 60 |
2 | 79, 10, 30 |
5 | 79, 5, 15 |
79, 1, 3 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 79 x 1 x 3 = 4740
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 14/4740
Therefore, the GCF of Fractions 56/79,56/20,882/60 is 14/4740
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 79,20,60 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,20,60) = 1
common factors(in case of two or more numbers have common factors) = 20
GCF(79,20,60) x common factors =1 x 20 = 20
LCM(79,20,60) = ( 79 × 20 × 60 ) / 20
LCM(79,20,60) = 94800 / 20
LCM(79,20,60) = 4740
