Given numbers are 557,842,748,834
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 557,842,748,834 is 73143366252.
Find LCM of 557,842,748,834 with Prime Factorization
| 2 | 557, 842, 748, 834 |
| 557, 421, 374, 417 |
Multiply the prime numbers at the bottom and the left side.
2 x 557 x 421 x 374 x 417 = 73143366252
Therefore, the lowest common multiple of 557,842,748,834 is 73143366252.
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.
557 x 842 x 748 x 834 = 292573465008
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.
557 : 1, 557
842 : 1, 2, 421, 842
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
834 : 1, 2, 3, 6, 139, 278, 417, 834
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 557,842,748,834, is 1.
Now, the common factors can be found like this.
557:557
842:2x 421
748:2x 2x 11x 17
834:2x 3x 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 2 = 4
Therefore, the value for common factors is 4.
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 = 292573465008/(1x4)
LCM = 292573465008/4
LCM = 73143366252
Thus, we can understand that the LCM of 557,842,748,834 is 73143366252.
