The LCM of 567,810,531,642 is 35794710.
Find LCM of 567,810,531,642 with Prime Factorization
| 2 | 567, 810, 531, 642 |
| 3 | 567, 405, 531, 321 |
| 3 | 189, 135, 177, 107 |
| 3 | 63, 45, 59, 107 |
| 3 | 21, 15, 59, 107 |
| 7, 5, 59, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 7 x 5 x 59 x 107 = 35794710
Therefore, the lowest common multiple of 567,810,531,642 is 35794710.
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.
567 x 810 x 531 x 642 = 156566061540
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.
567 : 1, 3, 7, 9, 21, 27, 63, 81, 189, 567
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
531 : 1, 3, 9, 59, 177, 531
642 : 1, 2, 3, 6, 107, 214, 321, 642
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 567,810,531,642, is 3.
Now, the common factors can be found like this.
567:3x 3x 3x 3x 7
810:2x 3x 3x 3x 3x 5
531:3x 3x 59
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 3x 3 = 1458
Therefore, the value for common factors is 1458.
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 = 156566061540/(3x1458)
LCM = 156566061540/4374
LCM = 35794710
Thus, we can understand that the LCM of 567,810,531,642 is 35794710.
