2 | 670, 672 |
335, 336 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 670
:1,2,5,10,67,134,335,670
Now, list down the factors of 672
:1,2,3,4,6,7,8,12,14,16,21,24,28,32,42,48,56,84,96,112,168,224,336,672
Greatest Common Factor
We found the factors 670,672 . The biggest common factor number is the GCF number.
So the greatest common factor 670,672 is 2.
Lets's calculate LCM of 109,930
Given numbers has no common factors except 1. So, there LCM is their product i.e 101370
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/101370
Therefore, the GCF of Fractions 670/109,672/930 is 2/101370
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 109,930 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(109,930) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(109,930) x common factors =1 x 1 = 1
LCM(109,930) = ( 109 × 930 ) / 1
LCM(109,930) = 101370 / 1
LCM(109,930) = 101370
