Given numbers are 570,321,450,765
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 570,321,450,765 is 15552450.
Find LCM of 570,321,450,765 with Prime Factorization
| 2 | 570, 321, 450, 765 |
| 3 | 285, 321, 225, 765 |
| 3 | 95, 107, 75, 255 |
| 5 | 95, 107, 25, 85 |
| 19, 107, 5, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 19 x 107 x 5 x 17 = 15552450
Therefore, the lowest common multiple of 570,321,450,765 is 15552450.
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 321 x 450 x 765 = 62987422500
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
321 : 1, 3, 107, 321
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 570,321,450,765, is 3.
Now, the common factors can be found like this.
570:2x 3x 5x 19
321:3x 107
450:2x 3x 3x 5x 5
765:3x 3x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5x 5 = 1350
Therefore, the value for common factors is 1350.
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 = 62987422500/(3x1350)
LCM = 62987422500/4050
LCM = 15552450
Thus, we can understand that the LCM of 570,321,450,765 is 15552450.
