Now, list down the factors of 810
:1,2,3,5,6,9,10,15,18,27,30,45,54,81,90,135,162,270,405,810
Greatest Common Factor
We found the factors 79,77,810 . The biggest common factor number is the GCF number.
So the greatest common factor 79,77,810 is 1.
Lets's calculate LCM of 42,76,970
2 | 42, 76, 970 |
21, 38, 485 |
∴ So the LCM of the given numbers is 2 x 21 x 38 x 485 = 774060
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/774060
Therefore, the GCF of Fractions 79/42,77/76,810/970 is 1/774060
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 42,76,970 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,76,970) = 2
common factors(in case of two or more numbers have common factors) = 2
GCF(42,76,970) x common factors =2 x 2 = 4
LCM(42,76,970) = ( 42 × 76 × 970 ) / 4
LCM(42,76,970) = 3096240 / 4
LCM(42,76,970) = 774060
