:1,991
Greatest Common Factor
We found the factors 318,991 . The biggest common factor number is the GCF number.
So the greatest common factor 318,991 is 1.
Lets's calculate LCM of 742,142
2 | 742, 142 |
371, 71 |
∴ So the LCM of the given numbers is 2 x 371 x 71 = 52682
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/52682
Therefore, the GCF of Fractions 318/742,991/142 is 1/52682
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 742,142 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(742,142) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(742,142) x common factors =2 x 1 = 2
LCM(742,142) = ( 742 × 142 ) / 2
LCM(742,142) = 105364 / 2
LCM(742,142) = 52682
