Greatest Common Factor
We found the factors 6,64,67,839 . The biggest common factor number is the GCF number.
So the greatest common factor 6,64,67,839 is 1.
Lets's calculate LCM of 30,91,169,642
2 | 30, 91, 169, 642 |
3 | 15, 91, 169, 321 |
13 | 5, 91, 169, 107 |
5, 7, 13, 107 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 5 x 7 x 13 x 107 = 3797430
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3797430
Therefore, the GCF of Fractions 6/30,64/91,67/169,839/642 is 1/3797430
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 30,91,169,642 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,91,169,642) = 1
common factors(in case of two or more numbers have common factors) = 78
GCF(30,91,169,642) x common factors =1 x 78 = 78
LCM(30,91,169,642) = ( 30 × 91 × 169 × 642 ) / 78
LCM(30,91,169,642) = 296199540 / 78
LCM(30,91,169,642) = 3797430
