Given numbers are 920,411,715,338
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 920,411,715,338 is 702925080.
Find LCM of 920,411,715,338 with Prime Factorization
| 2 | 920, 411, 715, 338 |
| 5 | 460, 411, 715, 169 |
| 13 | 92, 411, 143, 169 |
| 92, 411, 11, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 92 x 411 x 11 x 13 = 702925080
Therefore, the lowest common multiple of 920,411,715,338 is 702925080.
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.
920 x 411 x 715 x 338 = 91380260400
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
411 : 1, 3, 137, 411
715 : 1, 5, 11, 13, 55, 65, 143, 715
338 : 1, 2, 13, 26, 169, 338
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,411,715,338, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
411:3x 137
715:5x 11x 13
338:2x 13x 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 = 91380260400/(1x130)
LCM = 91380260400/130
LCM = 702925080
Thus, we can understand that the LCM of 920,411,715,338 is 702925080.
