Given numbers are 715,724,810,638,802
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,724,810,638,802 is 487609319340.
Find LCM of 715,724,810,638,802 with Prime Factorization
| 2 | 715, 724, 810, 638, 802 |
| 5 | 715, 362, 405, 319, 401 |
| 11 | 143, 362, 81, 319, 401 |
| 13, 362, 81, 29, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 13 x 362 x 81 x 29 x 401 = 487609319340
Therefore, the lowest common multiple of 715,724,810,638,802 is 487609319340.
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 724 x 810 x 638 x 802 = 214548100509600
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
724 : 1, 2, 4, 181, 362, 724
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
638 : 1, 2, 11, 22, 29, 58, 319, 638
802 : 1, 2, 401, 802
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,724,810,638,802, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
724:2x 2x 181
810:2x 3x 3x 3x 3x 5
638:2x 11x 29
802:2x 401
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 2x 5x 11 = 440
Therefore, the value for common factors is 440.
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 = 214548100509600/(1x440)
LCM = 214548100509600/440
LCM = 487609319340
Thus, we can understand that the LCM of 715,724,810,638,802 is 487609319340.
