Lets's calculate LCM of 68,77,70
2 | 68, 77, 70 |
7 | 34, 77, 35 |
34, 11, 5 |
∴ So the LCM of the given numbers is 2 x 7 x 34 x 11 x 5 = 26180
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/26180
Therefore, the GCF of Fractions 4/68,712/77,892/70 is 4/26180
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 68,77,70 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(68,77,70) = 1
common factors(in case of two or more numbers have common factors) = 14
GCF(68,77,70) x common factors =1 x 14 = 14
LCM(68,77,70) = ( 68 × 77 × 70 ) / 14
LCM(68,77,70) = 366520 / 14
LCM(68,77,70) = 26180
