Given numbers are 920,644,657,793,508
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 920,644,657,793,508 is 426116297880.
Find LCM of 920,644,657,793,508 with Prime Factorization
| 2 | 920, 644, 657, 793, 508 |
| 2 | 460, 322, 657, 793, 254 |
| 23 | 230, 161, 657, 793, 127 |
| 10, 7, 657, 793, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 10 x 7 x 657 x 793 x 127 = 426116297880
Therefore, the lowest common multiple of 920,644,657,793,508 is 426116297880.
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.
920 x 644 x 657 x 793 x 508 = 156810797619840
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
657 : 1, 3, 9, 73, 219, 657
793 : 1, 13, 61, 793
508 : 1, 2, 4, 127, 254, 508
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,644,657,793,508, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
644:2x 2x 7x 23
657:3x 3x 73
793:13x 61
508:2x 2x 127
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 23 = 368
Therefore, the value for common factors is 368.
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 = 156810797619840/(1x368)
LCM = 156810797619840/368
LCM = 426116297880
Thus, we can understand that the LCM of 920,644,657,793,508 is 426116297880.
