Greatest Common Factor
We found the factors 70,66,42,14 . The biggest common factor number is the GCF number.
So the greatest common factor 70,66,42,14 is 2.
Lets's calculate LCM of 57,76,96,661
2 | 57, 76, 96, 661 |
2 | 57, 38, 48, 661 |
3 | 57, 19, 24, 661 |
19 | 19, 19, 8, 661 |
1, 1, 8, 661 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 19 x 1 x 1 x 8 x 661 = 1205664
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/1205664
Therefore, the GCF of Fractions 70/57,66/76,42/96,14/661 is 2/1205664
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 57,76,96,661 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(57,76,96,661) = 1
common factors(in case of two or more numbers have common factors) = 228
GCF(57,76,96,661) x common factors =1 x 228 = 228
LCM(57,76,96,661) = ( 57 × 76 × 96 × 661 ) / 228
LCM(57,76,96,661) = 274891392 / 228
LCM(57,76,96,661) = 1205664
