Given numbers are 231,440,782,621,439
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 231,440,782,621,439 is 14274330840.
Find LCM of 231,440,782,621,439 with Prime Factorization
| 2 | 231, 440, 782, 621, 439 |
| 3 | 231, 220, 391, 621, 439 |
| 11 | 77, 220, 391, 207, 439 |
| 23 | 7, 20, 391, 207, 439 |
| 7, 20, 17, 9, 439 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 23 x 7 x 20 x 17 x 9 x 439 = 14274330840
Therefore, the lowest common multiple of 231,440,782,621,439 is 14274330840.
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.
231 x 440 x 782 x 621 x 439 = 21668434215120
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
782 : 1, 2, 17, 23, 34, 46, 391, 782
621 : 1, 3, 9, 23, 27, 69, 207, 621
439 : 1, 439
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,440,782,621,439, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
440:2x 2x 2x 5x 11
782:2x 17x 23
621:3x 3x 3x 23
439:439
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 11x 23 = 1518
Therefore, the value for common factors is 1518.
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 = 21668434215120/(1x1518)
LCM = 21668434215120/1518
LCM = 14274330840
Thus, we can understand that the LCM of 231,440,782,621,439 is 14274330840.
