Given numbers are 676,280,540,785
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 676,280,540,785 is 200589480.
Find LCM of 676,280,540,785 with Prime Factorization
| 2 | 676, 280, 540, 785 |
| 2 | 338, 140, 270, 785 |
| 5 | 169, 70, 135, 785 |
| 169, 14, 27, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 169 x 14 x 27 x 157 = 200589480
Therefore, the lowest common multiple of 676,280,540,785 is 200589480.
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.
676 x 280 x 540 x 785 = 80235792000
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
785 : 1, 5, 157, 785
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 676,280,540,785, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
280:2x 2x 2x 5x 7
540:2x 2x 3x 3x 3x 5
785:5x 157
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 5x 5 = 400
Therefore, the value for common factors is 400.
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 = 80235792000/(1x400)
LCM = 80235792000/400
LCM = 200589480
Thus, we can understand that the LCM of 676,280,540,785 is 200589480.
