Greatest Common Factor
We found the factors 762,643,978 . The biggest common factor number is the GCF number.
So the greatest common factor 762,643,978 is 1.
Lets's calculate LCM of 81,68,121
Given numbers has no common factors except 1. So, there LCM is their product i.e 666468
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/666468
Therefore, the GCF of Fractions 762/81,643/68,978/121 is 1/666468
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 81,68,121 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,68,121) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(81,68,121) x common factors =1 x 1 = 1
LCM(81,68,121) = ( 81 × 68 × 121 ) / 1
LCM(81,68,121) = 666468 / 1
LCM(81,68,121) = 666468
