So the greatest common factor 21,36,565 is 1.
Lets's calculate LCM of 556,229,624
2 | 556, 229, 624 |
2 | 278, 229, 312 |
139, 229, 156 |
∴ So the LCM of the given numbers is 2 x 2 x 139 x 229 x 156 = 19862544
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/19862544
Therefore, the GCF of Fractions 21/556,36/229,565/624 is 1/19862544
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 556,229,624 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(556,229,624) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(556,229,624) x common factors =1 x 4 = 4
LCM(556,229,624) = ( 556 × 229 × 624 ) / 4
LCM(556,229,624) = 79450176 / 4
LCM(556,229,624) = 19862544
