Lets's calculate LCM of 170,7670
2 | 170, 7670 |
5 | 85, 3835 |
17, 767 |
∴ So the LCM of the given numbers is 2 x 5 x 17 x 767 = 130390
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/130390
Therefore, the GCF of Fractions 1918/170,1145/7670 is 1/130390
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 170,7670 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(170,7670) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(170,7670) x common factors =10 x 1 = 10
LCM(170,7670) = ( 170 × 7670 ) / 10
LCM(170,7670) = 1303900 / 10
LCM(170,7670) = 130390
