Greatest Common Factor
We found the factors 7,86,40 . The biggest common factor number is the GCF number.
So the greatest common factor 7,86,40 is 1.
Lets's calculate LCM of 70,216,584
2 | 70, 216, 584 |
2 | 35, 108, 292 |
2 | 35, 54, 146 |
35, 27, 73 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 35 x 27 x 73 = 551880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/551880
Therefore, the GCF of Fractions 7/70,86/216,40/584 is 1/551880
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 70,216,584 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,216,584) = 2
common factors(in case of two or more numbers have common factors) = 8
GCF(70,216,584) x common factors =2 x 8 = 16
LCM(70,216,584) = ( 70 × 216 × 584 ) / 16
LCM(70,216,584) = 8830080 / 16
LCM(70,216,584) = 551880
