Greatest Common Factor
We found the factors 73,60,89,31 . The biggest common factor number is the GCF number.
So the greatest common factor 73,60,89,31 is 1.
Lets's calculate LCM of 42,28,94,18
2 | 42, 28, 94, 18 |
3 | 21, 14, 47, 9 |
7 | 7, 14, 47, 3 |
1, 2, 47, 3 |
∴ So the LCM of the given numbers is 2 x 3 x 7 x 1 x 2 x 47 x 3 = 11844
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/11844
Therefore, the GCF of Fractions 73/42,60/28,89/94,31/18 is 1/11844
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 42,28,94,18 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,28,94,18) = 2
common factors(in case of two or more numbers have common factors) = 84
GCF(42,28,94,18) x common factors =2 x 84 = 168
LCM(42,28,94,18) = ( 42 × 28 × 94 × 18 ) / 168
LCM(42,28,94,18) = 1989792 / 168
LCM(42,28,94,18) = 11844
