Given numbers are 779,285,455,462
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 779,285,455,462 is 23393370.
Find LCM of 779,285,455,462 with Prime Factorization
| 3 | 779, 285, 455, 462 |
| 5 | 779, 95, 455, 154 |
| 7 | 779, 19, 91, 154 |
| 19 | 779, 19, 13, 22 |
| 41, 1, 13, 22 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 19 x 41 x 1 x 13 x 22 = 23393370
Therefore, the lowest common multiple of 779,285,455,462 is 23393370.
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.
779 x 285 x 455 x 462 = 46669773150
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.
779 : 1, 19, 41, 779
285 : 1, 3, 5, 15, 19, 57, 95, 285
455 : 1, 5, 7, 13, 35, 65, 91, 455
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,285,455,462, is 1.
Now, the common factors can be found like this.
779:19x 41
285:3x 5x 19
455:5x 7x 13
462:2x 3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7x 19 = 1995
Therefore, the value for common factors is 1995.
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 = 46669773150/(1x1995)
LCM = 46669773150/1995
LCM = 23393370
Thus, we can understand that the LCM of 779,285,455,462 is 23393370.
