The LCM of 931,644,662,490,792 is 28067303880.
Find LCM of 931,644,662,490,792 with Prime Factorization
| 2 | 931, 644, 662, 490, 792 |
| 2 | 931, 322, 331, 245, 396 |
| 7 | 931, 161, 331, 245, 198 |
| 7 | 133, 23, 331, 35, 198 |
| 19, 23, 331, 5, 198 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 7 x 19 x 23 x 331 x 5 x 198 = 28067303880
Therefore, the lowest common multiple of 931,644,662,490,792 is 28067303880.
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 644 x 662 x 490 x 792 = 154033363693440
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
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
662 : 1, 2, 331, 662
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,644,662,490,792, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
644:2x 2x 7x 23
662:2x 331
490:2x 5x 7x 7
792:2x 2x 2x 3x 3x 11
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 7x 7x 7 = 5488
Therefore, the value for common factors is 5488.
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 = 154033363693440/(1x5488)
LCM = 154033363693440/5488
LCM = 28067303880
Thus, we can understand that the LCM of 931,644,662,490,792 is 28067303880.
