Given numbers are 338,834,780,784,724
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 338,834,780,784,724 is 50002002960.
Find LCM of 338,834,780,784,724 with Prime Factorization
| 2 | 338, 834, 780, 784, 724 |
| 2 | 169, 417, 390, 392, 362 |
| 3 | 169, 417, 195, 196, 181 |
| 13 | 169, 139, 65, 196, 181 |
| 13, 139, 5, 196, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 13 x 139 x 5 x 196 x 181 = 50002002960
Therefore, the lowest common multiple of 338,834,780,784,724 is 50002002960.
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.
338 x 834 x 780 x 784 x 724 = 124804999388160
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.
338 : 1, 2, 13, 26, 169, 338
834 : 1, 2, 3, 6, 139, 278, 417, 834
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
724 : 1, 2, 4, 181, 362, 724
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,834,780,784,724, is 2.
Now, the common factors can be found like this.
338:2x 13x 13
834:2x 3x 139
780:2x 2x 3x 5x 13
784:2x 2x 2x 2x 7x 7
724:2x 2x 181
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 2x 2x 3x 13 = 1248
Therefore, the value for common factors is 1248.
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 = 124804999388160/(2x1248)
LCM = 124804999388160/2496
LCM = 50002002960
Thus, we can understand that the LCM of 338,834,780,784,724 is 50002002960.
