2 | 780, 676 |
2 | 390, 338 |
13 | 195, 169 |
15, 13 |
∴ So the LCM of the given numbers is 2 x 2 x 13 x 15 x 13 = 10140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/10140
Therefore, the GCF of Fractions 3080/780,7139/676 is 11/10140
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 780,676 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(780,676) = 52
common factors(in case of two or more numbers have common factors) = 1
GCF(780,676) x common factors =52 x 1 = 52
LCM(780,676) = ( 780 × 676 ) / 52
LCM(780,676) = 527280 / 52
LCM(780,676) = 10140
