Given numbers are 780,140,589,165
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 780,140,589,165 is 35375340.
Find LCM of 780,140,589,165 with Prime Factorization
| 2 | 780, 140, 589, 165 |
| 2 | 390, 70, 589, 165 |
| 3 | 195, 35, 589, 165 |
| 5 | 65, 35, 589, 55 |
| 13, 7, 589, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 7 x 589 x 11 = 35375340
Therefore, the lowest common multiple of 780,140,589,165 is 35375340.
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.
780 x 140 x 589 x 165 = 10612602000
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.
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
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
589 : 1, 19, 31, 589
165 : 1, 3, 5, 11, 15, 33, 55, 165
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,140,589,165, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
140:2x 2x 5x 7
589:19x 31
165:3x 5x 11
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 3x 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 10612602000/(1x300)
LCM = 10612602000/300
LCM = 35375340
Thus, we can understand that the LCM of 780,140,589,165 is 35375340.
