The LCM of 838,453,572,858 is 108569604.
Find LCM of 838,453,572,858 with Prime Factorization
| 2 | 838, 453, 572, 858 |
| 3 | 419, 453, 286, 429 |
| 11 | 419, 151, 286, 143 |
| 13 | 419, 151, 26, 13 |
| 419, 151, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 13 x 419 x 151 x 2 x 1 = 108569604
Therefore, the lowest common multiple of 838,453,572,858 is 108569604.
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.
838 x 453 x 572 x 858 = 186305440464
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.
838 : 1, 2, 419, 838
453 : 1, 3, 151, 453
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,453,572,858, is 1.
Now, the common factors can be found like this.
838:2x 419
453:3x 151
572:2x 2x 11x 13
858:2x 3x 11x 13
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 3x 11x 13 = 1716
Therefore, the value for common factors is 1716.
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 = 186305440464/(1x1716)
LCM = 186305440464/1716
LCM = 108569604
Thus, we can understand that the LCM of 838,453,572,858 is 108569604.
