Greatest Common Factor
We found the factors 92,74,31,47 . The biggest common factor number is the GCF number.
So the greatest common factor 92,74,31,47 is 1.
Lets's calculate LCM of 65,78,74,84
2 | 65, 78, 74, 84 |
3 | 65, 39, 37, 42 |
13 | 65, 13, 37, 14 |
5, 1, 37, 14 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 5 x 1 x 37 x 14 = 202020
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/202020
Therefore, the GCF of Fractions 92/65,74/78,31/74,47/84 is 1/202020
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 65,78,74,84 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(65,78,74,84) = 1
common factors(in case of two or more numbers have common factors) = 156
GCF(65,78,74,84) x common factors =1 x 156 = 156
LCM(65,78,74,84) = ( 65 × 78 × 74 × 84 ) / 156
LCM(65,78,74,84) = 31515120 / 156
LCM(65,78,74,84) = 202020
