1,2,17,34,53,106,901,1802
Greatest Common Factor
We found the factors 70,1802 . The biggest common factor number is the GCF number.
So the greatest common factor 70,1802 is 2.
Lets's calculate LCM of 420,8668
2 | 420, 8668 |
2 | 210, 4334 |
105, 2167 |
∴ So the LCM of the given numbers is 2 x 2 x 105 x 2167 = 910140
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/910140
Therefore, the GCF of Fractions 70/420,1802/8668 is 2/910140
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 420,8668 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(420,8668) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(420,8668) x common factors =4 x 1 = 4
LCM(420,8668) = ( 420 × 8668 ) / 4
LCM(420,8668) = 3640560 / 4
LCM(420,8668) = 910140
