Given numbers are 506,515,738,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 506,515,738,720 is 769261680.
Find LCM of 506,515,738,720 with Prime Factorization
| 2 | 506, 515, 738, 720 |
| 3 | 253, 515, 369, 360 |
| 3 | 253, 515, 123, 120 |
| 5 | 253, 515, 41, 40 |
| 253, 103, 41, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 253 x 103 x 41 x 8 = 769261680
Therefore, the lowest common multiple of 506,515,738,720 is 769261680.
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.
506 x 515 x 738 x 720 = 138467102400
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.
506 : 1, 2, 11, 22, 23, 46, 253, 506
515 : 1, 5, 103, 515
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 506,515,738,720, is 1.
Now, the common factors can be found like this.
506:2x 11x 23
515:5x 103
738:2x 3x 3x 41
720:2x 2x 2x 2x 3x 3x 5
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 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 138467102400/(1x180)
LCM = 138467102400/180
LCM = 769261680
Thus, we can understand that the LCM of 506,515,738,720 is 769261680.
