Given numbers are 731,638,236,190,531
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,638,236,190,531 is 47052876420.
Find LCM of 731,638,236,190,531 with Prime Factorization
| 2 | 731, 638, 236, 190, 531 |
| 59 | 731, 319, 118, 95, 531 |
| 731, 319, 2, 95, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 59 x 731 x 319 x 2 x 95 x 9 = 47052876420
Therefore, the lowest common multiple of 731,638,236,190,531 is 47052876420.
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.
731 x 638 x 236 x 190 x 531 = 11104478835120
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.
731 : 1, 17, 43, 731
638 : 1, 2, 11, 22, 29, 58, 319, 638
236 : 1, 2, 4, 59, 118, 236
190 : 1, 2, 5, 10, 19, 38, 95, 190
531 : 1, 3, 9, 59, 177, 531
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,638,236,190,531, is 1.
Now, the common factors can be found like this.
731:17x 43
638:2x 11x 29
236:2x 2x 59
190:2x 5x 19
531:3x 3x 59
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 59 = 236
Therefore, the value for common factors is 236.
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 = 11104478835120/(1x236)
LCM = 11104478835120/236
LCM = 47052876420
Thus, we can understand that the LCM of 731,638,236,190,531 is 47052876420.
