Given numbers are 639,353,802,715,520
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,353,802,715,520 is 517387539240.
Find LCM of 639,353,802,715,520 with Prime Factorization
| 2 | 639, 353, 802, 715, 520 |
| 5 | 639, 353, 401, 715, 260 |
| 13 | 639, 353, 401, 143, 52 |
| 639, 353, 401, 11, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 639 x 353 x 401 x 11 x 4 = 517387539240
Therefore, the lowest common multiple of 639,353,802,715,520 is 517387539240.
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.
639 x 353 x 802 x 715 x 520 = 67260380101200
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.
639 : 1, 3, 9, 71, 213, 639
353 : 1, 353
802 : 1, 2, 401, 802
715 : 1, 5, 11, 13, 55, 65, 143, 715
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,353,802,715,520, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
353:353
802:2x 401
715:5x 11x 13
520:2x 2x 2x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 67260380101200/(1x130)
LCM = 67260380101200/130
LCM = 517387539240
Thus, we can understand that the LCM of 639,353,802,715,520 is 517387539240.
