So the greatest common factor 28,62,774 is 2.
Lets's calculate LCM of 201,977,781
Given numbers has no common factors except 1. So, there LCM is their product i.e 153370437
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/153370437
Therefore, the GCF of Fractions 28/201,62/977,774/781 is 2/153370437
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 201,977,781 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(201,977,781) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(201,977,781) x common factors =1 x 1 = 1
LCM(201,977,781) = ( 201 × 977 × 781 ) / 1
LCM(201,977,781) = 153370437 / 1
LCM(201,977,781) = 153370437
