The LCM of 437,152,892,418,638 is 248694952.
Find LCM of 437,152,892,418,638 with Prime Factorization
| 2 | 437, 152, 892, 418, 638 |
| 2 | 437, 76, 446, 209, 319 |
| 11 | 437, 38, 223, 209, 319 |
| 19 | 437, 38, 223, 19, 29 |
| 23, 2, 223, 1, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 19 x 23 x 2 x 223 x 1 x 29 = 248694952
Therefore, the lowest common multiple of 437,152,892,418,638 is 248694952.
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.
437 x 152 x 892 x 418 x 638 = 15801082470272
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.
437 : 1, 19, 23, 437
152 : 1, 2, 4, 8, 19, 38, 76, 152
892 : 1, 2, 4, 223, 446, 892
418 : 1, 2, 11, 19, 22, 38, 209, 418
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,152,892,418,638, is 1.
Now, the common factors can be found like this.
437:19x 23
152:2x 2x 2x 19
892:2x 2x 223
418:2x 11x 19
638:2x 11x 29
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 11x 19x 19 = 63536
Therefore, the value for common factors is 63536.
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 = 15801082470272/(1x63536)
LCM = 15801082470272/63536
LCM = 248694952
Thus, we can understand that the LCM of 437,152,892,418,638 is 248694952.
