Given numbers are 838,637,637,629
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,637,637,629 is 335763974.
Find LCM of 838,637,637,629 with Prime Factorization
| 7 | 838, 637, 637, 629 |
| 7 | 838, 91, 91, 629 |
| 13 | 838, 13, 13, 629 |
| 838, 1, 1, 629 |
Multiply the prime numbers at the bottom and the left side.
7 x 7 x 13 x 838 x 1 x 1 x 629 = 335763974
Therefore, the lowest common multiple of 838,637,637,629 is 335763974.
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 637 x 637 x 629 = 213881651438
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
637 : 1, 7, 13, 49, 91, 637
637 : 1, 7, 13, 49, 91, 637
629 : 1, 17, 37, 629
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,637,637,629, is 1.
Now, the common factors can be found like this.
838:2x 419
637:7x 7x 13
637:7x 7x 13
629:17x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7x 13 = 637
Therefore, the value for common factors is 637.
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 = 213881651438/(1x637)
LCM = 213881651438/637
LCM = 335763974
Thus, we can understand that the LCM of 838,637,637,629 is 335763974.
