Greatest Common Factor
We found the factors 40,75,59,20 . The biggest common factor number is the GCF number.
So the greatest common factor 40,75,59,20 is 1.
Lets's calculate LCM of 78,39,99,76
2 | 78, 39, 99, 76 |
3 | 39, 39, 99, 38 |
13 | 13, 13, 33, 38 |
1, 1, 33, 38 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 1 x 1 x 33 x 38 = 97812
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/97812
Therefore, the GCF of Fractions 40/78,75/39,59/99,20/76 is 1/97812
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 78,39,99,76 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,39,99,76) = 1
common factors(in case of two or more numbers have common factors) = 234
GCF(78,39,99,76) x common factors =1 x 234 = 234
LCM(78,39,99,76) = ( 78 × 39 × 99 × 76 ) / 234
LCM(78,39,99,76) = 22888008 / 234
LCM(78,39,99,76) = 97812
