So the greatest common factor 83,415,616 is 1.
Lets's calculate LCM of 934,712,420
2 | 934, 712, 420 |
2 | 467, 356, 210 |
467, 178, 105 |
∴ So the LCM of the given numbers is 2 x 2 x 467 x 178 x 105 = 34912920
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/34912920
Therefore, the GCF of Fractions 83/934,415/712,616/420 is 1/34912920
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 934,712,420 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(934,712,420) = 2
common factors(in case of two or more numbers have common factors) = 4
GCF(934,712,420) x common factors =2 x 4 = 8
LCM(934,712,420) = ( 934 × 712 × 420 ) / 8
LCM(934,712,420) = 279303360 / 8
LCM(934,712,420) = 34912920
