So the greatest common factor 38,795,385 is 1.
Lets's calculate LCM of 980,306,863
2 | 980, 306, 863 |
490, 153, 863 |
∴ So the LCM of the given numbers is 2 x 490 x 153 x 863 = 129398220
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/129398220
Therefore, the GCF of Fractions 38/980,795/306,385/863 is 1/129398220
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 980,306,863 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(980,306,863) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(980,306,863) x common factors =1 x 2 = 2
LCM(980,306,863) = ( 980 × 306 × 863 ) / 2
LCM(980,306,863) = 258796440 / 2
LCM(980,306,863) = 129398220
