So the greatest common factor 972,160,690 is 2.
Lets's calculate LCM of 28,63,308
2 | 28, 63, 308 |
2 | 14, 63, 154 |
7 | 7, 63, 77 |
1, 9, 11 |
∴ So the LCM of the given numbers is 2 x 2 x 7 x 1 x 9 x 11 = 2772
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2772
Therefore, the GCF of Fractions 972/28,160/63,690/308 is 2/2772
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 28,63,308 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,63,308) = 7
common factors(in case of two or more numbers have common factors) = 28
GCF(28,63,308) x common factors =7 x 28 = 196
LCM(28,63,308) = ( 28 × 63 × 308 ) / 196
LCM(28,63,308) = 543312 / 196
LCM(28,63,308) = 2772
