:1,2,991,1982
Greatest Common Factor
We found the factors 700,1982 . The biggest common factor number is the GCF number.
So the greatest common factor 700,1982 is 2.
Lets's calculate LCM of 671,781
11 | 671, 781 |
61, 71 |
∴ So the LCM of the given numbers is 11 x 61 x 71 = 47641
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/47641
Therefore, the GCF of Fractions 700/671,1982/781 is 2/47641
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 671,781 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(671,781) = 11
common factors(in case of two or more numbers have common factors) = 1
GCF(671,781) x common factors =11 x 1 = 11
LCM(671,781) = ( 671 × 781 ) / 11
LCM(671,781) = 524051 / 11
LCM(671,781) = 47641
