Lets's calculate GCF of 429,813
3 | 429, 813 |
143, 271 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 429
:1,3,11,13,33,39,143,429
Now, list down the factors of 813
:1,3,271,813
Greatest Common Factor
We found the factors 429,813 . The biggest common factor number is the GCF number.
So the greatest common factor 429,813 is 3.
Lets's calculate LCM of 602,745
Given numbers has no common factors except 1. So, there LCM is their product i.e 448490
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/448490
Therefore, the GCF of Fractions 429/602,813/745 is 3/448490
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 602,745 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(602,745) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(602,745) x common factors =1 x 1 = 1
LCM(602,745) = ( 602 × 745 ) / 1
LCM(602,745) = 448490 / 1
LCM(602,745) = 448490
