Given numbers are 957,723,180,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 957,723,180,720 is 55352880.
Find LCM of 957,723,180,720 with Prime Factorization
| 2 | 957, 723, 180, 720 |
| 2 | 957, 723, 90, 360 |
| 3 | 957, 723, 45, 180 |
| 3 | 319, 241, 15, 60 |
| 5 | 319, 241, 5, 20 |
| 319, 241, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 319 x 241 x 1 x 4 = 55352880
Therefore, the lowest common multiple of 957,723,180,720 is 55352880.
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.
957 x 723 x 180 x 720 = 89671665600
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.
957 : 1, 3, 11, 29, 33, 87, 319, 957
723 : 1, 3, 241, 723
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 957,723,180,720, is 3.
Now, the common factors can be found like this.
957:3x 11x 29
723:3x 241
180:2x 2x 3x 3x 5
720:2x 2x 2x 2x 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 3x 3x 5 = 540
Therefore, the value for common factors is 540.
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 = 89671665600/(3x540)
LCM = 89671665600/1620
LCM = 55352880
Thus, we can understand that the LCM of 957,723,180,720 is 55352880.
