Given numbers are 634,540,702,723
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 634,540,702,723 is 536306940.
Find LCM of 634,540,702,723 with Prime Factorization
| 2 | 634, 540, 702, 723 |
| 3 | 317, 270, 351, 723 |
| 3 | 317, 90, 117, 241 |
| 3 | 317, 30, 39, 241 |
| 317, 10, 13, 241 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 317 x 10 x 13 x 241 = 536306940
Therefore, the lowest common multiple of 634,540,702,723 is 536306940.
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.
634 x 540 x 702 x 723 = 173763448560
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.
634 : 1, 2, 317, 634
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
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
723 : 1, 3, 241, 723
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 634,540,702,723, is 1.
Now, the common factors can be found like this.
634:2x 317
540:2x 2x 3x 3x 3x 5
702:2x 3x 3x 3x 13
723:3x 241
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 3x 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 173763448560/(1x324)
LCM = 173763448560/324
LCM = 536306940
Thus, we can understand that the LCM of 634,540,702,723 is 536306940.
