Lets's calculate LCM of 786,642
2 | 786, 642 |
3 | 393, 321 |
131, 107 |
∴ So the LCM of the given numbers is 2 x 3 x 131 x 107 = 84102
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/84102
Therefore, the GCF of Fractions 158/786,6904/642 is 2/84102
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 786,642 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(786,642) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(786,642) x common factors =6 x 1 = 6
LCM(786,642) = ( 786 × 642 ) / 6
LCM(786,642) = 504612 / 6
LCM(786,642) = 84102
