Given numbers are 684,480,180,772
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 684,480,180,772 is 5280480.
Find LCM of 684,480,180,772 with Prime Factorization
| 2 | 684, 480, 180, 772 |
| 2 | 342, 240, 90, 386 |
| 3 | 171, 120, 45, 193 |
| 3 | 57, 40, 15, 193 |
| 5 | 19, 40, 5, 193 |
| 19, 8, 1, 193 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 19 x 8 x 1 x 193 = 5280480
Therefore, the lowest common multiple of 684,480,180,772 is 5280480.
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.
684 x 480 x 180 x 772 = 45623347200
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
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
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
772 : 1, 2, 4, 193, 386, 772
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,480,180,772, is 4.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
480:2x 2x 2x 2x 2x 3x 5
180:2x 2x 3x 3x 5
772:2x 2x 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 2x 3x 3x 3x 5 = 2160
Therefore, the value for common factors is 2160.
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 = 45623347200/(4x2160)
LCM = 45623347200/8640
LCM = 5280480
Thus, we can understand that the LCM of 684,480,180,772 is 5280480.
