Given numbers are 207,570,813,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 207,570,813,780 is 277119180.
Find LCM of 207,570,813,780 with Prime Factorization
| 2 | 207, 570, 813, 780 |
| 3 | 207, 285, 813, 390 |
| 5 | 69, 95, 271, 130 |
| 69, 19, 271, 26 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 69 x 19 x 271 x 26 = 277119180
Therefore, the lowest common multiple of 207,570,813,780 is 277119180.
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.
207 x 570 x 813 x 780 = 74822178600
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.
207 : 1, 3, 9, 23, 69, 207
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
813 : 1, 3, 271, 813
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
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 207,570,813,780, is 3.
Now, the common factors can be found like this.
207:3x 3x 23
570:2x 3x 5x 19
813:3x 271
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 3x 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 74822178600/(3x90)
LCM = 74822178600/270
LCM = 277119180
Thus, we can understand that the LCM of 207,570,813,780 is 277119180.
