Lets's calculate LCM of 238,7721
7 | 238, 7721 |
34, 1103 |
∴ So the LCM of the given numbers is 7 x 34 x 1103 = 262514
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 49/262514
Therefore, the GCF of Fractions 637/238,4018/7721 is 49/262514
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 238,7721 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(238,7721) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(238,7721) x common factors =7 x 1 = 7
LCM(238,7721) = ( 238 × 7721 ) / 7
LCM(238,7721) = 1837598 / 7
LCM(238,7721) = 262514
