We found the factors 320,776,172 . The biggest common factor number is the GCF number.
So the greatest common factor 320,776,172 is 4.
Lets's calculate LCM of 33,77,92
11 | 33, 77, 92 |
3, 7, 92 |
∴ So the LCM of the given numbers is 11 x 3 x 7 x 92 = 21252
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/21252
Therefore, the GCF of Fractions 320/33,776/77,172/92 is 4/21252
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 33,77,92 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(33,77,92) = 1
common factors(in case of two or more numbers have common factors) = 11
GCF(33,77,92) x common factors =1 x 11 = 11
LCM(33,77,92) = ( 33 × 77 × 92 ) / 11
LCM(33,77,92) = 233772 / 11
LCM(33,77,92) = 21252
