The factors of 251 are 1, 251
The HCF of 205,251 is 1.
Lets's calculate GCF of 205,251
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 205
:1,5,41,205
Now, list down the factors of 251
:1,251
Greatest Common Factor
We found the factors 205,251 . The biggest common factor number is the GCF number.
So the greatest common factor 205,251 is 1.
Lets's calculate LCM of 780,603
3 | 780, 603 |
260, 201 |
∴ So the LCM of the given numbers is 3 x 260 x 201 = 156780
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/156780
Therefore, the GCF of Fractions 205/780,251/603 is 1/156780
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 780,603 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(780,603) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(780,603) x common factors =3 x 1 = 3
LCM(780,603) = ( 780 × 603 ) / 3
LCM(780,603) = 470340 / 3
LCM(780,603) = 156780
