Lets's calculate LCM of 475,736,685
5 | 475, 736, 685 |
95, 736, 137 |
∴ So the LCM of the given numbers is 5 x 95 x 736 x 137 = 47895200
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/47895200
Therefore, the GCF of Fractions 840/475,185/736,220/685 is 5/47895200
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 475,736,685 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(475,736,685) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(475,736,685) x common factors =1 x 5 = 5
LCM(475,736,685) = ( 475 × 736 × 685 ) / 5
LCM(475,736,685) = 239476000 / 5
LCM(475,736,685) = 47895200
