Given numbers are 574,665,621,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 574,665,621,720 is 270905040.
Find LCM of 574,665,621,720 with Prime Factorization
| 2 | 574, 665, 621, 720 |
| 3 | 287, 665, 621, 360 |
| 3 | 287, 665, 207, 120 |
| 5 | 287, 665, 69, 40 |
| 7 | 287, 133, 69, 8 |
| 41, 19, 69, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 41 x 19 x 69 x 8 = 270905040
Therefore, the lowest common multiple of 574,665,621,720 is 270905040.
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.
574 x 665 x 621 x 720 = 170670175200
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.
574 : 1, 2, 7, 14, 41, 82, 287, 574
665 : 1, 5, 7, 19, 35, 95, 133, 665
621 : 1, 3, 9, 23, 27, 69, 207, 621
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 574,665,621,720, is 1.
Now, the common factors can be found like this.
574:2x 7x 41
665:5x 7x 19
621:3x 3x 3x 23
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 3x 3x 5x 7 = 630
Therefore, the value for common factors is 630.
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 = 170670175200/(1x630)
LCM = 170670175200/630
LCM = 270905040
Thus, we can understand that the LCM of 574,665,621,720 is 270905040.
