Given numbers are 627,418,478,428,178
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 627,418,478,428,178 is 5708200476.
Find LCM of 627,418,478,428,178 with Prime Factorization
| 2 | 627, 418, 478, 428, 178 |
| 11 | 627, 209, 239, 214, 89 |
| 19 | 57, 19, 239, 214, 89 |
| 3, 1, 239, 214, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 19 x 3 x 1 x 239 x 214 x 89 = 5708200476
Therefore, the lowest common multiple of 627,418,478,428,178 is 5708200476.
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.
627 x 418 x 478 x 428 x 178 = 9544111195872
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.
627 : 1, 3, 11, 19, 33, 57, 209, 627
418 : 1, 2, 11, 19, 22, 38, 209, 418
478 : 1, 2, 239, 478
428 : 1, 2, 4, 107, 214, 428
178 : 1, 2, 89, 178
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 627,418,478,428,178, is 1.
Now, the common factors can be found like this.
627:3x 11x 19
418:2x 11x 19
478:2x 239
428:2x 2x 107
178:2x 89
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 11x 19 = 1672
Therefore, the value for common factors is 1672.
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 = 9544111195872/(1x1672)
LCM = 9544111195872/1672
LCM = 5708200476
Thus, we can understand that the LCM of 627,418,478,428,178 is 5708200476.
