Given numbers are 620,676,394,793,434
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 620,676,394,793,434 is 8813988820.
Find LCM of 620,676,394,793,434 with Prime Factorization
| 2 | 620, 676, 394, 793, 434 |
| 2 | 310, 338, 197, 793, 217 |
| 13 | 155, 169, 197, 793, 217 |
| 31 | 155, 13, 197, 61, 217 |
| 5, 13, 197, 61, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 31 x 5 x 13 x 197 x 61 x 7 = 8813988820
Therefore, the lowest common multiple of 620,676,394,793,434 is 8813988820.
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.
620 x 676 x 394 x 793 x 434 = 56832599911360
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
394 : 1, 2, 197, 394
793 : 1, 13, 61, 793
434 : 1, 2, 7, 14, 31, 62, 217, 434
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,676,394,793,434, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
676:2x 2x 13x 13
394:2x 197
793:13x 61
434:2x 7x 31
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 13x 31 = 6448
Therefore, the value for common factors is 6448.
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 = 56832599911360/(1x6448)
LCM = 56832599911360/6448
LCM = 8813988820
Thus, we can understand that the LCM of 620,676,394,793,434 is 8813988820.
