1,2,4,8,13,16,26,32,52,104,208,416
Greatest Common Factor
We found the factors 142,661,416 . The biggest common factor number is the GCF number.
So the greatest common factor 142,661,416 is 1.
Lets's calculate LCM of 19,17,438
Given numbers has no common factors except 1. So, there LCM is their product i.e 141474
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/141474
Therefore, the GCF of Fractions 142/19,661/17,416/438 is 1/141474
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 19,17,438 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,17,438) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(19,17,438) x common factors =1 x 1 = 1
LCM(19,17,438) = ( 19 × 17 × 438 ) / 1
LCM(19,17,438) = 141474 / 1
LCM(19,17,438) = 141474
