So the greatest common factor 86,78,154 is 2.
Lets's calculate LCM of 722,622,683
2 | 722, 622, 683 |
361, 311, 683 |
∴ So the LCM of the given numbers is 2 x 361 x 311 x 683 = 153362186
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/153362186
Therefore, the GCF of Fractions 86/722,78/622,154/683 is 2/153362186
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 722,622,683 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(722,622,683) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(722,622,683) x common factors =1 x 2 = 2
LCM(722,622,683) = ( 722 × 622 × 683 ) / 2
LCM(722,622,683) = 306724372 / 2
LCM(722,622,683) = 153362186
