Given numbers are 720,648,493,579
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 720,648,493,579 is 616565520.
Find LCM of 720,648,493,579 with Prime Factorization
| 2 | 720, 648, 493, 579 |
| 2 | 360, 324, 493, 579 |
| 2 | 180, 162, 493, 579 |
| 3 | 90, 81, 493, 579 |
| 3 | 30, 27, 493, 193 |
| 10, 9, 493, 193 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 10 x 9 x 493 x 193 = 616565520
Therefore, the lowest common multiple of 720,648,493,579 is 616565520.
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.
720 x 648 x 493 x 579 = 133178152320
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.
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
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
493 : 1, 17, 29, 493
579 : 1, 3, 193, 579
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,648,493,579, is 1.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
648:2x 2x 2x 3x 3x 3x 3
493:17x 29
579:3x 193
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 2x 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 133178152320/(1x216)
LCM = 133178152320/216
LCM = 616565520
Thus, we can understand that the LCM of 720,648,493,579 is 616565520.
