Given numbers are 451,787,256,654,436
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 451,787,256,654,436 is 29712486144.
Find LCM of 451,787,256,654,436 with Prime Factorization
| 2 | 451, 787, 256, 654, 436 |
| 2 | 451, 787, 128, 327, 218 |
| 109 | 451, 787, 64, 327, 109 |
| 451, 787, 64, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 109 x 451 x 787 x 64 x 3 x 1 = 29712486144
Therefore, the lowest common multiple of 451,787,256,654,436 is 29712486144.
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.
451 x 787 x 256 x 654 x 436 = 25909287917568
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.
451 : 1, 11, 41, 451
787 : 1, 787
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
654 : 1, 2, 3, 6, 109, 218, 327, 654
436 : 1, 2, 4, 109, 218, 436
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 451,787,256,654,436, is 1.
Now, the common factors can be found like this.
451:11x 41
787:787
256:2x 2x 2x 2x 2x 2x 2x 2
654:2x 3x 109
436:2x 2x 109
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 109 = 872
Therefore, the value for common factors is 872.
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 = 25909287917568/(1x872)
LCM = 25909287917568/872
LCM = 29712486144
Thus, we can understand that the LCM of 451,787,256,654,436 is 29712486144.
