Given numbers are 570,394,943,656
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 570,394,943,656 is 847115760.
Find LCM of 570,394,943,656 with Prime Factorization
| 2 | 570, 394, 943, 656 |
| 41 | 285, 197, 943, 328 |
| 285, 197, 23, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 41 x 285 x 197 x 23 x 8 = 847115760
Therefore, the lowest common multiple of 570,394,943,656 is 847115760.
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.
570 x 394 x 943 x 656 = 138926984640
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.
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
394 : 1, 2, 197, 394
943 : 1, 23, 41, 943
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 570,394,943,656, is 1.
Now, the common factors can be found like this.
570:2x 3x 5x 19
394:2x 197
943:23x 41
656:2x 2x 2x 2x 41
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 41 = 164
Therefore, the value for common factors is 164.
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 = 138926984640/(1x164)
LCM = 138926984640/164
LCM = 847115760
Thus, we can understand that the LCM of 570,394,943,656 is 847115760.
