Given numbers are 531,706,457,758,540
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 531,706,457,758,540 is 1947941395740.
Find LCM of 531,706,457,758,540 with Prime Factorization
| 2 | 531, 706, 457, 758, 540 |
| 3 | 531, 353, 457, 379, 270 |
| 3 | 177, 353, 457, 379, 90 |
| 59, 353, 457, 379, 30 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 59 x 353 x 457 x 379 x 30 = 1947941395740
Therefore, the lowest common multiple of 531,706,457,758,540 is 1947941395740.
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.
531 x 706 x 457 x 758 x 540 = 70125890246640
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.
531 : 1, 3, 9, 59, 177, 531
706 : 1, 2, 353, 706
457 : 1, 457
758 : 1, 2, 379, 758
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 531,706,457,758,540, is 1.
Now, the common factors can be found like this.
531:3x 3x 59
706:2x 353
457:457
758:2x 379
540:2x 2x 3x 3x 3x 5
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 70125890246640/(1x36)
LCM = 70125890246640/36
LCM = 1947941395740
Thus, we can understand that the LCM of 531,706,457,758,540 is 1947941395740.
