Given numbers are 931,676,637,400
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 931,676,637,400 is 62935600.
Find LCM of 931,676,637,400 with Prime Factorization
| 2 | 931, 676, 637, 400 |
| 2 | 931, 338, 637, 200 |
| 7 | 931, 169, 637, 100 |
| 7 | 133, 169, 91, 100 |
| 13 | 19, 169, 13, 100 |
| 19, 1, 13, 100 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 7 x 13 x 19 x 1 x 13 x 100 = 62935600
Therefore, the lowest common multiple of 931,676,637,400 is 62935600.
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.
931 x 676 x 637 x 400 = 160359908800
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.
931 : 1, 7, 19, 49, 133, 931
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
637 : 1, 7, 13, 49, 91, 637
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,676,637,400, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
676:2x 2x 13x 13
637:7x 7x 13
400:2x 2x 2x 2x 5x 5
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 7x 7x 13 = 2548
Therefore, the value for common factors is 2548.
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 = 160359908800/(1x2548)
LCM = 160359908800/2548
LCM = 62935600
Thus, we can understand that the LCM of 931,676,637,400 is 62935600.
