Given numbers are 910,647,420,793
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 910,647,420,793 is 215489820.
Find LCM of 910,647,420,793 with Prime Factorization
| 2 | 910, 647, 420, 793 |
| 5 | 455, 647, 210, 793 |
| 7 | 91, 647, 42, 793 |
| 13 | 13, 647, 6, 793 |
| 1, 647, 6, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 13 x 1 x 647 x 6 x 61 = 215489820
Therefore, the lowest common multiple of 910,647,420,793 is 215489820.
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.
910 x 647 x 420 x 793 = 196095736200
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.
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
647 : 1, 647
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
793 : 1, 13, 61, 793
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 910,647,420,793, is 1.
Now, the common factors can be found like this.
910:2x 5x 7x 13
647:647
420:2x 2x 3x 5x 7
793:13x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 13 = 910
Therefore, the value for common factors is 910.
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 = 196095736200/(1x910)
LCM = 196095736200/910
LCM = 215489820
Thus, we can understand that the LCM of 910,647,420,793 is 215489820.
