Greatest Common Factor
We found the factors 700,8820 . The biggest common factor number is the GCF number.
So the greatest common factor 700,8820 is 140.
Lets's calculate LCM of 750,490
2 | 750, 490 |
5 | 375, 245 |
75, 49 |
∴ So the LCM of the given numbers is 2 x 5 x 75 x 49 = 36750
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 140/36750
Therefore, the GCF of Fractions 700/750,8820/490 is 140/36750
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 750,490 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(750,490) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(750,490) x common factors =10 x 1 = 10
LCM(750,490) = ( 750 × 490 ) / 10
LCM(750,490) = 367500 / 10
LCM(750,490) = 36750
