Given numbers are 834,748,800,784
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 834,748,800,784 is 3056776800.
Find LCM of 834,748,800,784 with Prime Factorization
| 2 | 834, 748, 800, 784 |
| 2 | 417, 374, 400, 392 |
| 2 | 417, 187, 200, 196 |
| 2 | 417, 187, 100, 98 |
| 417, 187, 50, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 417 x 187 x 50 x 49 = 3056776800
Therefore, the lowest common multiple of 834,748,800,784 is 3056776800.
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.
834 x 748 x 800 x 784 = 391267430400
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.
834 : 1, 2, 3, 6, 139, 278, 417, 834
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 834,748,800,784, is 2.
Now, the common factors can be found like this.
834:2x 3x 139
748:2x 2x 11x 17
800:2x 2x 2x 2x 2x 5x 5
784:2x 2x 2x 2x 7x 7
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 2 = 64
Therefore, the value for common factors is 64.
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 = 391267430400/(2x64)
LCM = 391267430400/128
LCM = 3056776800
Thus, we can understand that the LCM of 834,748,800,784 is 3056776800.
