The LCM of 715,726,450,689 is 37516050.
Find LCM of 715,726,450,689 with Prime Factorization
| 2 | 715, 726, 450, 689 |
| 3 | 715, 363, 225, 689 |
| 5 | 715, 121, 75, 689 |
| 11 | 143, 121, 15, 689 |
| 13 | 13, 11, 15, 689 |
| 1, 11, 15, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 13 x 1 x 11 x 15 x 53 = 37516050
Therefore, the lowest common multiple of 715,726,450,689 is 37516050.
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.
715 x 726 x 450 x 689 = 160943854500
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,726,450,689, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
726:2x 3x 11x 11
450:2x 3x 3x 5x 5
689:13x 53
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 5x 11x 13 = 4290
Therefore, the value for common factors is 4290.
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 = 160943854500/(1x4290)
LCM = 160943854500/4290
LCM = 37516050
Thus, we can understand that the LCM of 715,726,450,689 is 37516050.
