Lets's calculate LCM of 456,764
2 | 456, 764 |
2 | 228, 382 |
114, 191 |
∴ So the LCM of the given numbers is 2 x 2 x 114 x 191 = 87096
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/87096
Therefore, the GCF of Fractions 133/456,4242/764 is 7/87096
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 456,764 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(456,764) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(456,764) x common factors =4 x 1 = 4
LCM(456,764) = ( 456 × 764 ) / 4
LCM(456,764) = 348384 / 4
LCM(456,764) = 87096
