Given numbers are 570,640,762,589
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 570,640,762,589 is 143621760.
Find LCM of 570,640,762,589 with Prime Factorization
| 2 | 570, 640, 762, 589 |
| 3 | 285, 320, 381, 589 |
| 5 | 95, 320, 127, 589 |
| 19 | 19, 64, 127, 589 |
| 1, 64, 127, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 1 x 64 x 127 x 31 = 143621760
Therefore, the lowest common multiple of 570,640,762,589 is 143621760.
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.
570 x 640 x 762 x 589 = 163728806400
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.
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
762 : 1, 2, 3, 6, 127, 254, 381, 762
589 : 1, 19, 31, 589
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 570,640,762,589, is 1.
Now, the common factors can be found like this.
570:2x 3x 5x 19
640:2x 2x 2x 2x 2x 2x 2x 5
762:2x 3x 127
589:19x 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 3x 5x 19 = 1140
Therefore, the value for common factors is 1140.
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 = 163728806400/(1x1140)
LCM = 163728806400/1140
LCM = 143621760
Thus, we can understand that the LCM of 570,640,762,589 is 143621760.
