So the greatest common factor 860,742,621 is 1.
Lets's calculate LCM of 70,61,192
| 2 | 70, 61, 192 |
| 35, 61, 96 |
∴ So the LCM of the given numbers is 2 x 35 x 61 x 96 = 409920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/409920
Therefore, the GCF of Fractions 860/70,742/61,621/192 is 1/409920
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 70,61,192 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,61,192) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(70,61,192) x common factors =1 x 2 = 2
LCM(70,61,192) = ( 70 × 61 × 192 ) / 2
LCM(70,61,192) = 819840 / 2
LCM(70,61,192) = 409920
