Greatest Common Factor
We found the factors 40,78,882 . The biggest common factor number is the GCF number.
So the greatest common factor 40,78,882 is 2.
Lets's calculate LCM of 78,832,840
2 | 78, 832, 840 |
2 | 39, 416, 420 |
2 | 39, 208, 210 |
3 | 39, 104, 105 |
13 | 13, 104, 35 |
1, 8, 35 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 13 x 1 x 8 x 35 = 87360
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/87360
Therefore, the GCF of Fractions 40/78,78/832,882/840 is 2/87360
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 78,832,840 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,832,840) = 2
common factors(in case of two or more numbers have common factors) = 312
GCF(78,832,840) x common factors =2 x 312 = 624
LCM(78,832,840) = ( 78 × 832 × 840 ) / 624
LCM(78,832,840) = 54512640 / 624
LCM(78,832,840) = 87360
