We found the factors 860,4640 . The biggest common factor number is the GCF number.
So the greatest common factor 860,4640 is 20.
Lets's calculate LCM of 49,742
7 | 49, 742 |
7, 106 |
∴ So the LCM of the given numbers is 7 x 7 x 106 = 5194
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/5194
Therefore, the GCF of Fractions 860/49,4640/742 is 20/5194
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 49,742 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(49,742) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(49,742) x common factors =7 x 1 = 7
LCM(49,742) = ( 49 × 742 ) / 7
LCM(49,742) = 36358 / 7
LCM(49,742) = 5194
