Given numbers are 834,784,872,973
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 834,784,872,973 is 35635152.
Find LCM of 834,784,872,973 with Prime Factorization
| 2 | 834, 784, 872, 973 |
| 2 | 417, 392, 436, 973 |
| 2 | 417, 196, 218, 973 |
| 7 | 417, 98, 109, 973 |
| 139 | 417, 14, 109, 139 |
| 3, 14, 109, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 139 x 3 x 14 x 109 x 1 = 35635152
Therefore, the lowest common multiple of 834,784,872,973 is 35635152.
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 784 x 872 x 973 = 554768046336
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
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
872 : 1, 2, 4, 8, 109, 218, 436, 872
973 : 1, 7, 139, 973
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 834,784,872,973, is 1.
Now, the common factors can be found like this.
834:2x 3x 139
784:2x 2x 2x 2x 7x 7
872:2x 2x 2x 109
973:7x 139
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 7x 139 = 15568
Therefore, the value for common factors is 15568.
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 = 554768046336/(1x15568)
LCM = 554768046336/15568
LCM = 35635152
Thus, we can understand that the LCM of 834,784,872,973 is 35635152.
