Greatest Common Factor
We found the factors 7,74,11,262 . The biggest common factor number is the GCF number.
So the greatest common factor 7,74,11,262 is 1.
Lets's calculate LCM of 74,21,220,618
2 | 74, 21, 220, 618 |
3 | 37, 21, 110, 309 |
37, 7, 110, 103 |
∴ So the LCM of the given numbers is 2 x 3 x 37 x 7 x 110 x 103 = 17606820
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/17606820
Therefore, the GCF of Fractions 7/74,74/21,11/220,262/618 is 1/17606820
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 74,21,220,618 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(74,21,220,618) = 1
common factors(in case of two or more numbers have common factors) = 12
GCF(74,21,220,618) x common factors =1 x 12 = 12
LCM(74,21,220,618) = ( 74 × 21 × 220 × 618 ) / 12
LCM(74,21,220,618) = 211281840 / 12
LCM(74,21,220,618) = 17606820
