Given numbers are 500,338,406,695,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 500,338,406,695,642 is 765372016500.
Find LCM of 500,338,406,695,642 with Prime Factorization
| 2 | 500, 338, 406, 695, 642 |
| 5 | 250, 169, 203, 695, 321 |
| 50, 169, 203, 139, 321 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 50 x 169 x 203 x 139 x 321 = 765372016500
Therefore, the lowest common multiple of 500,338,406,695,642 is 765372016500.
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.
500 x 338 x 406 x 695 x 642 = 30614880660000
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.
500 : 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500
338 : 1, 2, 13, 26, 169, 338
406 : 1, 2, 7, 14, 29, 58, 203, 406
695 : 1, 5, 139, 695
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 500,338,406,695,642, is 1.
Now, the common factors can be found like this.
500:2x 2x 5x 5x 5
338:2x 13x 13
406:2x 7x 29
695:5x 139
642:2x 3x 107
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 5 = 40
Therefore, the value for common factors is 40.
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 = 30614880660000/(1x40)
LCM = 30614880660000/40
LCM = 765372016500
Thus, we can understand that the LCM of 500,338,406,695,642 is 765372016500.
