So the greatest common factor 689,549,639 is 1.
Lets's calculate LCM of 665,152,151
19 | 665, 152, 151 |
35, 8, 151 |
∴ So the LCM of the given numbers is 19 x 35 x 8 x 151 = 803320
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/803320
Therefore, the GCF of Fractions 689/665,549/152,639/151 is 1/803320
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 665,152,151 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(665,152,151) = 1
common factors(in case of two or more numbers have common factors) = 19
GCF(665,152,151) x common factors =1 x 19 = 19
LCM(665,152,151) = ( 665 × 152 × 151 ) / 19
LCM(665,152,151) = 15263080 / 19
LCM(665,152,151) = 803320
