So the greatest common factor 490,784,295 is 1.
Lets's calculate LCM of 749,749,220
7 | 749, 749, 220 |
107 | 107, 107, 220 |
1, 1, 220 |
∴ So the LCM of the given numbers is 7 x 107 x 1 x 1 x 220 = 164780
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/164780
Therefore, the GCF of Fractions 490/749,784/749,295/220 is 1/164780
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 749,749,220 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(749,749,220) = 1
common factors(in case of two or more numbers have common factors) = 749
GCF(749,749,220) x common factors =1 x 749 = 749
LCM(749,749,220) = ( 749 × 749 × 220 ) / 749
LCM(749,749,220) = 123420220 / 749
LCM(749,749,220) = 164780
