Lets's calculate LCM of 716,420
2 | 716, 420 |
2 | 358, 210 |
179, 105 |
∴ So the LCM of the given numbers is 2 x 2 x 179 x 105 = 75180
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/75180
Therefore, the GCF of Fractions 436/716,520/420 is 4/75180
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 716,420 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(716,420) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(716,420) x common factors =4 x 1 = 4
LCM(716,420) = ( 716 × 420 ) / 4
LCM(716,420) = 300720 / 4
LCM(716,420) = 75180
