Given numbers are 660,480,641,934
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 660,480,641,934 is 1580552160.
Find LCM of 660,480,641,934 with Prime Factorization
| 2 | 660, 480, 641, 934 |
| 2 | 330, 240, 641, 467 |
| 3 | 165, 120, 641, 467 |
| 5 | 55, 40, 641, 467 |
| 11, 8, 641, 467 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 8 x 641 x 467 = 1580552160
Therefore, the lowest common multiple of 660,480,641,934 is 1580552160.
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.
660 x 480 x 641 x 934 = 189666259200
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.
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
641 : 1, 641
934 : 1, 2, 467, 934
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,480,641,934, is 1.
Now, the common factors can be found like this.
660:2x 2x 3x 5x 11
480:2x 2x 2x 2x 2x 3x 5
641:641
934:2x 467
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 5 = 120
Therefore, the value for common factors is 120.
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 = 189666259200/(1x120)
LCM = 189666259200/120
LCM = 1580552160
Thus, we can understand that the LCM of 660,480,641,934 is 1580552160.
