So the greatest common factor 936,588,616 is 4.
Lets's calculate LCM of 42,40,70
2 | 42, 40, 70 |
5 | 21, 20, 35 |
7 | 21, 4, 7 |
3, 4, 1 |
∴ So the LCM of the given numbers is 2 x 5 x 7 x 3 x 4 x 1 = 840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/840
Therefore, the GCF of Fractions 936/42,588/40,616/70 is 4/840
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 42,40,70 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,40,70) = 2
common factors(in case of two or more numbers have common factors) = 70
GCF(42,40,70) x common factors =2 x 70 = 140
LCM(42,40,70) = ( 42 × 40 × 70 ) / 140
LCM(42,40,70) = 117600 / 140
LCM(42,40,70) = 840
