So the greatest common factor 22,921,162 is 1.
Lets's calculate LCM of 28,56,212
2 | 28, 56, 212 |
2 | 14, 28, 106 |
7 | 7, 14, 53 |
1, 2, 53 |
∴ So the LCM of the given numbers is 2 x 2 x 7 x 1 x 2 x 53 = 2968
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2968
Therefore, the GCF of Fractions 22/28,921/56,162/212 is 1/2968
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 28,56,212 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,56,212) = 4
common factors(in case of two or more numbers have common factors) = 28
GCF(28,56,212) x common factors =4 x 28 = 112
LCM(28,56,212) = ( 28 × 56 × 212 ) / 112
LCM(28,56,212) = 332416 / 112
LCM(28,56,212) = 2968
