Given numbers are 580,157,860,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 580,157,860,817 is 74396020.
Find LCM of 580,157,860,817 with Prime Factorization
| 2 | 580, 157, 860, 817 |
| 2 | 290, 157, 430, 817 |
| 5 | 145, 157, 215, 817 |
| 43 | 29, 157, 43, 817 |
| 29, 157, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 43 x 29 x 157 x 1 x 19 = 74396020
Therefore, the lowest common multiple of 580,157,860,817 is 74396020.
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.
580 x 157 x 860 x 817 = 63980577200
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.
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
157 : 1, 157
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 580,157,860,817, is 1.
Now, the common factors can be found like this.
580:2x 2x 5x 29
157:157
860:2x 2x 5x 43
817:19x 43
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 5x 43 = 860
Therefore, the value for common factors is 860.
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 = 63980577200/(1x860)
LCM = 63980577200/860
LCM = 74396020
Thus, we can understand that the LCM of 580,157,860,817 is 74396020.
