Greatest Common Factor
We found the factors 940,7320 . The biggest common factor number is the GCF number.
So the greatest common factor 940,7320 is 20.
Lets's calculate LCM of 78,740
2 | 78, 740 |
39, 370 |
∴ So the LCM of the given numbers is 2 x 39 x 370 = 28860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/28860
Therefore, the GCF of Fractions 940/78,7320/740 is 20/28860
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 78,740 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,740) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(78,740) x common factors =2 x 1 = 2
LCM(78,740) = ( 78 × 740 ) / 2
LCM(78,740) = 57720 / 2
LCM(78,740) = 28860
