Given numbers are 731,221,754,178
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,221,754,178 is 49054486.
Find LCM of 731,221,754,178 with Prime Factorization
| 2 | 731, 221, 754, 178 |
| 13 | 731, 221, 377, 89 |
| 17 | 731, 17, 29, 89 |
| 43, 1, 29, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 43 x 1 x 29 x 89 = 49054486
Therefore, the lowest common multiple of 731,221,754,178 is 49054486.
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 221 x 754 x 178 = 21682082812
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
221 : 1, 13, 17, 221
754 : 1, 2, 13, 26, 29, 58, 377, 754
178 : 1, 2, 89, 178
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,221,754,178, is 1.
Now, the common factors can be found like this.
731:17x 43
221:13x 17
754:2x 13x 29
178:2x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 17 = 442
Therefore, the value for common factors is 442.
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 = 21682082812/(1x442)
LCM = 21682082812/442
LCM = 49054486
Thus, we can understand that the LCM of 731,221,754,178 is 49054486.
