We found the factors 77,49,476 . The biggest common factor number is the GCF number.
So the greatest common factor 77,49,476 is 7.
Lets's calculate LCM of 40,624,863
2 | 40, 624, 863 |
2 | 20, 312, 863 |
2 | 10, 156, 863 |
5, 78, 863 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 78 x 863 = 2692560
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/2692560
Therefore, the GCF of Fractions 77/40,49/624,476/863 is 7/2692560
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 40,624,863 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,624,863) = 1
common factors(in case of two or more numbers have common factors) = 8
GCF(40,624,863) x common factors =1 x 8 = 8
LCM(40,624,863) = ( 40 × 624 × 863 ) / 8
LCM(40,624,863) = 21540480 / 8
LCM(40,624,863) = 2692560
