Given numbers are 637,931,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 637,931,494 is 24206.
Find LCM of 637,931,494 with Prime Factorization
| 7 | 637, 931, 494 |
| 7 | 91, 133, 494 |
| 13 | 13, 19, 494 |
| 19 | 1, 19, 38 |
| 1, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
7 x 7 x 13 x 19 x 1 x 1 x 2 = 24206
Therefore, the lowest common multiple of 637,931,494 is 24206.
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.
637 x 931 x 494 = 292965218
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.
637 : 1, 7, 13, 49, 91, 637
931 : 1, 7, 19, 49, 133, 931
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,931,494, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
931:7x 7x 19
494:2x 13x 19
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 13x 19 = 12103
Therefore, the value for common factors is 12103.
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 = 292965218/(1x12103)
LCM = 292965218/12103
LCM = 24206
Thus, we can understand that the LCM of 637,931,494 is 24206.
