So the greatest common factor 642,754 is 2.
Lets's calculate LCM of 362,898
2 | 362, 898 |
181, 449 |
∴ So the LCM of the given numbers is 2 x 181 x 449 = 162538
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/162538
Therefore, the GCF of Fractions 642/362,754/898 is 2/162538
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 362,898 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(362,898) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(362,898) x common factors =2 x 1 = 2
LCM(362,898) = ( 362 × 898 ) / 2
LCM(362,898) = 325076 / 2
LCM(362,898) = 162538
