Greatest Common Factor
We found the factors 33,52,61,79 . The biggest common factor number is the GCF number.
So the greatest common factor 33,52,61,79 is 1.
Lets's calculate LCM of 28,13,82,780
2 | 28, 13, 82, 780 |
2 | 14, 13, 41, 390 |
13 | 7, 13, 41, 195 |
7, 1, 41, 15 |
∴ So the LCM of the given numbers is 2 x 2 x 13 x 7 x 1 x 41 x 15 = 223860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/223860
Therefore, the GCF of Fractions 33/28,52/13,61/82,79/780 is 1/223860
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 28,13,82,780 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,13,82,780) = 1
common factors(in case of two or more numbers have common factors) = 104
GCF(28,13,82,780) x common factors =1 x 104 = 104
LCM(28,13,82,780) = ( 28 × 13 × 82 × 780 ) / 104
LCM(28,13,82,780) = 23281440 / 104
LCM(28,13,82,780) = 223860
