Lets's calculate LCM of 785,628
157 | 785, 628 |
5, 4 |
∴ So the LCM of the given numbers is 157 x 5 x 4 = 3140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/3140
Therefore, the GCF of Fractions 538/785,768/628 is 2/3140
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 785,628 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(785,628) = 157
common factors(in case of two or more numbers have common factors) = 1
GCF(785,628) x common factors =157 x 1 = 157
LCM(785,628) = ( 785 × 628 ) / 157
LCM(785,628) = 492980 / 157
LCM(785,628) = 3140
