Lets's calculate LCM of 350,364
2 | 350, 364 |
7 | 175, 182 |
25, 26 |
∴ So the LCM of the given numbers is 2 x 7 x 25 x 26 = 9100
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/9100
Therefore, the GCF of Fractions 638/350,1278/364 is 2/9100
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 350,364 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(350,364) = 14
common factors(in case of two or more numbers have common factors) = 1
GCF(350,364) x common factors =14 x 1 = 14
LCM(350,364) = ( 350 × 364 ) / 14
LCM(350,364) = 127400 / 14
LCM(350,364) = 9100
