Greatest Common Factor
We found the factors 152,778,820 . The biggest common factor number is the GCF number.
So the greatest common factor 152,778,820 is 2.
Lets's calculate LCM of 76,76,78
2 | 76, 76, 78 |
2 | 38, 38, 39 |
19 | 19, 19, 39 |
1, 1, 39 |
∴ So the LCM of the given numbers is 2 x 2 x 19 x 1 x 1 x 39 = 2964
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2964
Therefore, the GCF of Fractions 152/76,778/76,820/78 is 2/2964
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 76,76,78 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(76,76,78) = 2
common factors(in case of two or more numbers have common factors) = 76
GCF(76,76,78) x common factors =2 x 76 = 152
LCM(76,76,78) = ( 76 × 76 × 78 ) / 152
LCM(76,76,78) = 450528 / 152
LCM(76,76,78) = 2964
