Given numbers are 272,253,256,422
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 272,253,256,422 is 232322816.
Find LCM of 272,253,256,422 with Prime Factorization
| 2 | 272, 253, 256, 422 |
| 2 | 136, 253, 128, 211 |
| 2 | 68, 253, 64, 211 |
| 2 | 34, 253, 32, 211 |
| 17, 253, 16, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 17 x 253 x 16 x 211 = 232322816
Therefore, the lowest common multiple of 272,253,256,422 is 232322816.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
272 x 253 x 256 x 422 = 7434330112
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
253 : 1, 11, 23, 253
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
422 : 1, 2, 211, 422
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 272,253,256,422, is 1.
Now, the common factors can be found like this.
272:2x 2x 2x 2x 17
253:11x 23
256:2x 2x 2x 2x 2x 2x 2x 2
422:2x 211
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2 = 32
Therefore, the value for common factors is 32.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 7434330112/(1x32)
LCM = 7434330112/32
LCM = 232322816
Thus, we can understand that the LCM of 272,253,256,422 is 232322816.
