The LCM of 355,669,480,480 is 7599840.
Find LCM of 355,669,480,480 with Prime Factorization
| 2 | 355, 669, 480, 480 |
| 2 | 355, 669, 240, 240 |
| 2 | 355, 669, 120, 120 |
| 2 | 355, 669, 60, 60 |
| 2 | 355, 669, 30, 30 |
| 3 | 355, 669, 15, 15 |
| 5 | 355, 223, 5, 5 |
| 71, 223, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 5 x 71 x 223 x 1 x 1 = 7599840
Therefore, the lowest common multiple of 355,669,480,480 is 7599840.
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.
355 x 669 x 480 x 480 = 54718848000
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.
355 : 1, 5, 71, 355
669 : 1, 3, 223, 669
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
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,669,480,480, is 1.
Now, the common factors can be found like this.
355:5x 71
669:3x 223
480:2x 2x 2x 2x 2x 3x 5
480:2x 2x 2x 2x 2x 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 2x 2x 2x 3x 3x 5x 5 = 7200
Therefore, the value for common factors is 7200.
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 = 54718848000/(1x7200)
LCM = 54718848000/7200
LCM = 7599840
Thus, we can understand that the LCM of 355,669,480,480 is 7599840.
