Greatest Common Factor
We found the factors 82,66,74,21 . The biggest common factor number is the GCF number.
So the greatest common factor 82,66,74,21 is 1.
Lets's calculate LCM of 38,13,76,881
2 | 38, 13, 76, 881 |
19 | 19, 13, 38, 881 |
1, 13, 2, 881 |
∴ So the LCM of the given numbers is 2 x 19 x 1 x 13 x 2 x 881 = 870428
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/870428
Therefore, the GCF of Fractions 82/38,66/13,74/76,21/881 is 1/870428
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 38,13,76,881 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(38,13,76,881) = 1
common factors(in case of two or more numbers have common factors) = 38
GCF(38,13,76,881) x common factors =1 x 38 = 38
LCM(38,13,76,881) = ( 38 × 13 × 76 × 881 ) / 38
LCM(38,13,76,881) = 33076264 / 38
LCM(38,13,76,881) = 870428
