Lets's calculate GCF of 670,905
5 | 670, 905 |
134, 181 |
∴ So the GCF of the given numbers is 5 = 5
Now, list down the factors of 670
:1,2,5,10,67,134,335,670
Now, list down the factors of 905
:1,5,181,905
Greatest Common Factor
We found the factors 670,905 . The biggest common factor number is the GCF number.
So the greatest common factor 670,905 is 5.
Lets's calculate LCM of 156,919
Given numbers has no common factors except 1. So, there LCM is their product i.e 143364
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/143364
Therefore, the GCF of Fractions 670/156,905/919 is 5/143364
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 156,919 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(156,919) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(156,919) x common factors =1 x 1 = 1
LCM(156,919) = ( 156 × 919 ) / 1
LCM(156,919) = 143364 / 1
LCM(156,919) = 143364
