So the greatest common factor 256,7002 is 2.
Lets's calculate LCM of 888,840
2 | 888, 840 |
2 | 444, 420 |
2 | 222, 210 |
3 | 111, 105 |
37, 35 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 37 x 35 = 31080
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/31080
Therefore, the GCF of Fractions 256/888,7002/840 is 2/31080
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 888,840 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(888,840) = 24
common factors(in case of two or more numbers have common factors) = 1
GCF(888,840) x common factors =24 x 1 = 24
LCM(888,840) = ( 888 × 840 ) / 24
LCM(888,840) = 745920 / 24
LCM(888,840) = 31080
