Greatest Common Factor
We found the factors 98,80,77 . The biggest common factor number is the GCF number.
So the greatest common factor 98,80,77 is 1.
Lets's calculate LCM of 46,86,782
2 | 46, 86, 782 |
23 | 23, 43, 391 |
1, 43, 17 |
∴ So the LCM of the given numbers is 2 x 23 x 1 x 43 x 17 = 33626
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/33626
Therefore, the GCF of Fractions 98/46,80/86,77/782 is 1/33626
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 46,86,782 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(46,86,782) = 2
common factors(in case of two or more numbers have common factors) = 46
GCF(46,86,782) x common factors =2 x 46 = 92
LCM(46,86,782) = ( 46 × 86 × 782 ) / 92
LCM(46,86,782) = 3093592 / 92
LCM(46,86,782) = 33626
