So the greatest common factor 87,72,838 is 1.
Lets's calculate LCM of 628,710,701
2 | 628, 710, 701 |
314, 355, 701 |
∴ So the LCM of the given numbers is 2 x 314 x 355 x 701 = 156280940
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/156280940
Therefore, the GCF of Fractions 87/628,72/710,838/701 is 1/156280940
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 628,710,701 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(628,710,701) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(628,710,701) x common factors =1 x 2 = 2
LCM(628,710,701) = ( 628 × 710 × 701 ) / 2
LCM(628,710,701) = 312561880 / 2
LCM(628,710,701) = 156280940
