Given numbers are 621,186,780,791,184
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 621,186,780,791,184 is 7918321320.
Find LCM of 621,186,780,791,184 with Prime Factorization
| 2 | 621, 186, 780, 791, 184 |
| 2 | 621, 93, 390, 791, 92 |
| 3 | 621, 93, 195, 791, 46 |
| 23 | 207, 31, 65, 791, 46 |
| 9, 31, 65, 791, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 9 x 31 x 65 x 791 x 2 = 7918321320
Therefore, the lowest common multiple of 621,186,780,791,184 is 7918321320.
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.
621 x 186 x 780 x 791 x 184 = 13112740105920
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
186 : 1, 2, 3, 6, 31, 62, 93, 186
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
791 : 1, 7, 113, 791
184 : 1, 2, 4, 8, 23, 46, 92, 184
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,186,780,791,184, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
186:2x 3x 31
780:2x 2x 3x 5x 13
791:7x 113
184:2x 2x 2x 23
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 3x 3x 23 = 1656
Therefore, the value for common factors is 1656.
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 = 13112740105920/(1x1656)
LCM = 13112740105920/1656
LCM = 7918321320
Thus, we can understand that the LCM of 621,186,780,791,184 is 7918321320.
