So the greatest common factor 85,72,424 is 1.
Lets's calculate LCM of 140,725,224
2 | 140, 725, 224 |
2 | 70, 725, 112 |
5 | 35, 725, 56 |
7 | 7, 145, 56 |
1, 145, 8 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 7 x 1 x 145 x 8 = 162400
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/162400
Therefore, the GCF of Fractions 85/140,72/725,424/224 is 1/162400
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 140,725,224 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(140,725,224) = 1
common factors(in case of two or more numbers have common factors) = 140
GCF(140,725,224) x common factors =1 x 140 = 140
LCM(140,725,224) = ( 140 × 725 × 224 ) / 140
LCM(140,725,224) = 22736000 / 140
LCM(140,725,224) = 162400
