So the greatest common factor 553,406 is 7.
Lets's calculate LCM of 455,138
Given numbers has no common factors except 1. So, there LCM is their product i.e 62790
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/62790
Therefore, the GCF of Fractions 553/455,406/138 is 7/62790
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 455,138 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(455,138) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(455,138) x common factors =1 x 1 = 1
LCM(455,138) = ( 455 × 138 ) / 1
LCM(455,138) = 62790 / 1
LCM(455,138) = 62790
