Lets's calculate LCM of 782,440
2 | 782, 440 |
391, 220 |
∴ So the LCM of the given numbers is 2 x 391 x 220 = 172040
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 16/172040
Therefore, the GCF of Fractions 816/782,928/440 is 16/172040
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 782,440 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(782,440) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(782,440) x common factors =2 x 1 = 2
LCM(782,440) = ( 782 × 440 ) / 2
LCM(782,440) = 344080 / 2
LCM(782,440) = 172040
