Given numbers are 502,855,450,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 502,855,450,780 is 55797300.
Find LCM of 502,855,450,780 with Prime Factorization
| 2 | 502, 855, 450, 780 |
| 3 | 251, 855, 225, 390 |
| 3 | 251, 285, 75, 130 |
| 5 | 251, 95, 25, 130 |
| 251, 19, 5, 26 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 251 x 19 x 5 x 26 = 55797300
Therefore, the lowest common multiple of 502,855,450,780 is 55797300.
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.
502 x 855 x 450 x 780 = 150652710000
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.
502 : 1, 2, 251, 502
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 502,855,450,780, is 1.
Now, the common factors can be found like this.
502:2x 251
855:3x 3x 5x 19
450:2x 3x 3x 5x 5
780:2x 2x 3x 5x 13
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 3x 3x 3x 5x 5 = 2700
Therefore, the value for common factors is 2700.
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 = 150652710000/(1x2700)
LCM = 150652710000/2700
LCM = 55797300
Thus, we can understand that the LCM of 502,855,450,780 is 55797300.
