So the greatest common factor 48,36,76 is 4.
Lets's calculate LCM of 19,68,646
2 | 19, 68, 646 |
17 | 19, 34, 323 |
19 | 19, 2, 19 |
1, 2, 1 |
∴ So the LCM of the given numbers is 2 x 17 x 19 x 1 x 2 x 1 = 1292
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/1292
Therefore, the GCF of Fractions 48/19,36/68,76/646 is 4/1292
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 19,68,646 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,68,646) = 1
common factors(in case of two or more numbers have common factors) = 646
GCF(19,68,646) x common factors =1 x 646 = 646
LCM(19,68,646) = ( 19 × 68 × 646 ) / 646
LCM(19,68,646) = 834632 / 646
LCM(19,68,646) = 1292
