Lets's calculate LCM of 70,64,32,78
| 2 | 70, 64, 32, 78 |
| 2 | 35, 32, 16, 39 |
| 2 | 35, 8, 16, 39 |
| 2 | 35, 4, 8, 39 |
| 2 | 35, 2, 4, 39 |
| 35, 1, 2, 39 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 2 x 35 x 1 x 2 x 39 = 87360
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/87360
Therefore, the GCF of Fractions 63/70,79/64,11/32,46/78 is 1/87360
Least Common Multiple of 70,64,32,78 with GCF Formula
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 70,64,32,78 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,64,32,78) = 2
common factors(in case of two or more numbers have common factors) = 64
GCF(70,64,32,78) x common factors =2 x 64 = 128
LCM(70,64,32,78) = ( 70 × 64 × 32 × 78 ) / 128
LCM(70,64,32,78) = 11182080 / 128
LCM(70,64,32,78) = 87360
