Given numbers are 620,826,206,768,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 620,826,206,768,938 is 339277451520.
Find LCM of 620,826,206,768,938 with Prime Factorization
| 2 | 620, 826, 206, 768, 938 |
| 2 | 310, 413, 103, 384, 469 |
| 7 | 155, 413, 103, 192, 469 |
| 155, 59, 103, 192, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 155 x 59 x 103 x 192 x 67 = 339277451520
Therefore, the lowest common multiple of 620,826,206,768,938 is 339277451520.
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 826 x 206 x 768 x 938 = 75998149140480
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
826 : 1, 2, 7, 14, 59, 118, 413, 826
206 : 1, 2, 103, 206
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
938 : 1, 2, 7, 14, 67, 134, 469, 938
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,826,206,768,938, is 2.
Now, the common factors can be found like this.
620:2x 2x 5x 31
826:2x 7x 59
206:2x 103
768:2x 2x 2x 2x 2x 2x 2x 2x 3
938:2x 7x 67
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 7 = 112
Therefore, the value for common factors is 112.
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 = 75998149140480/(2x112)
LCM = 75998149140480/224
LCM = 339277451520
Thus, we can understand that the LCM of 620,826,206,768,938 is 339277451520.
