The factors of 851 are 1, 23, 37, 851
The HCF of 423,851 is 1.
Lets's calculate GCF of 423,851
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 423
:1,3,9,47,141,423
Now, list down the factors of 851
:1,23,37,851
Greatest Common Factor
We found the factors 423,851 . The biggest common factor number is the GCF number.
So the greatest common factor 423,851 is 1.
Lets's calculate LCM of 403,830
Given numbers has no common factors except 1. So, there LCM is their product i.e 334490
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/334490
Therefore, the GCF of Fractions 423/403,851/830 is 1/334490
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 403,830 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(403,830) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(403,830) x common factors =1 x 1 = 1
LCM(403,830) = ( 403 × 830 ) / 1
LCM(403,830) = 334490 / 1
LCM(403,830) = 334490
