Given numbers are 453,780,206,869,747
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 453,780,206,869,747 is 2624991480540.
Find LCM of 453,780,206,869,747 with Prime Factorization
| 2 | 453, 780, 206, 869, 747 |
| 3 | 453, 390, 103, 869, 747 |
| 151, 130, 103, 869, 249 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 151 x 130 x 103 x 869 x 249 = 2624991480540
Therefore, the lowest common multiple of 453,780,206,869,747 is 2624991480540.
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.
453 x 780 x 206 x 869 x 747 = 47249846649720
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.
453 : 1, 3, 151, 453
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
206 : 1, 2, 103, 206
869 : 1, 11, 79, 869
747 : 1, 3, 9, 83, 249, 747
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 453,780,206,869,747, is 1.
Now, the common factors can be found like this.
453:3x 151
780:2x 2x 3x 5x 13
206:2x 103
869:11x 79
747:3x 3x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 47249846649720/(1x18)
LCM = 47249846649720/18
LCM = 2624991480540
Thus, we can understand that the LCM of 453,780,206,869,747 is 2624991480540.
