Given numbers are 556,693,480,660
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,693,480,660 is 15412320.
Find LCM of 556,693,480,660 with Prime Factorization
| 2 | 556, 693, 480, 660 |
| 2 | 278, 693, 240, 330 |
| 3 | 139, 693, 120, 165 |
| 5 | 139, 231, 40, 55 |
| 11 | 139, 231, 8, 11 |
| 139, 21, 8, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 139 x 21 x 8 x 1 = 15412320
Therefore, the lowest common multiple of 556,693,480,660 is 15412320.
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.
556 x 693 x 480 x 660 = 122065574400
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.
556 : 1, 2, 4, 139, 278, 556
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
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
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,693,480,660, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
693:3x 3x 7x 11
480:2x 2x 2x 2x 2x 3x 5
660:2x 2x 3x 5x 11
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 2x 3x 3x 5x 11 = 7920
Therefore, the value for common factors is 7920.
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 = 122065574400/(1x7920)
LCM = 122065574400/7920
LCM = 15412320
Thus, we can understand that the LCM of 556,693,480,660 is 15412320.
