Given numbers are 591,639,781,864,151
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 591,639,781,864,151 is 20072799648.
Find LCM of 591,639,781,864,151 with Prime Factorization
| 3 | 591, 639, 781, 864, 151 |
| 3 | 197, 213, 781, 288, 151 |
| 71 | 197, 71, 781, 96, 151 |
| 197, 1, 11, 96, 151 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 71 x 197 x 1 x 11 x 96 x 151 = 20072799648
Therefore, the lowest common multiple of 591,639,781,864,151 is 20072799648.
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.
591 x 639 x 781 x 864 x 151 = 38479556925216
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.
591 : 1, 3, 197, 591
639 : 1, 3, 9, 71, 213, 639
781 : 1, 11, 71, 781
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
151 : 1, 151
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 591,639,781,864,151, is 1.
Now, the common factors can be found like this.
591:3x 197
639:3x 3x 71
781:11x 71
864:2x 2x 2x 2x 2x 3x 3x 3
151:151
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 71 = 1917
Therefore, the value for common factors is 1917.
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 = 38479556925216/(1x1917)
LCM = 38479556925216/1917
LCM = 20072799648
Thus, we can understand that the LCM of 591,639,781,864,151 is 20072799648.
