Given numbers are 387,649,670,671,956
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 387,649,670,671,956 is 4906685205180.
Find LCM of 387,649,670,671,956 with Prime Factorization
| 2 | 387, 649, 670, 671, 956 |
| 11 | 387, 649, 335, 671, 478 |
| 387, 59, 335, 61, 478 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 387 x 59 x 335 x 61 x 478 = 4906685205180
Therefore, the lowest common multiple of 387,649,670,671,956 is 4906685205180.
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.
387 x 649 x 670 x 671 x 956 = 107947074513960
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.
387 : 1, 3, 9, 43, 129, 387
649 : 1, 11, 59, 649
670 : 1, 2, 5, 10, 67, 134, 335, 670
671 : 1, 11, 61, 671
956 : 1, 2, 4, 239, 478, 956
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,649,670,671,956, is 1.
Now, the common factors can be found like this.
387:3x 3x 43
649:11x 59
670:2x 5x 67
671:11x 61
956:2x 2x 239
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 107947074513960/(1x22)
LCM = 107947074513960/22
LCM = 4906685205180
Thus, we can understand that the LCM of 387,649,670,671,956 is 4906685205180.
