Greatest Common Factor
We found the factors 38,68,57,483 . The biggest common factor number is the GCF number.
So the greatest common factor 38,68,57,483 is 1.
Lets's calculate LCM of 61,21,59,92
Given numbers has no common factors except 1. So, there LCM is their product i.e 6953268
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/6953268
Therefore, the GCF of Fractions 38/61,68/21,57/59,483/92 is 1/6953268
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 61,21,59,92 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(61,21,59,92) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(61,21,59,92) x common factors =1 x 1 = 1
LCM(61,21,59,92) = ( 61 × 21 × 59 × 92 ) / 1
LCM(61,21,59,92) = 6953268 / 1
LCM(61,21,59,92) = 6953268
