Given numbers are 731,559,153,356
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,559,153,356 is 30447612.
Find LCM of 731,559,153,356 with Prime Factorization
| 17 | 731, 559, 153, 356 |
| 43 | 43, 559, 9, 356 |
| 1, 13, 9, 356 |
Multiply the prime numbers at the bottom and the left side.
17 x 43 x 1 x 13 x 9 x 356 = 30447612
Therefore, the lowest common multiple of 731,559,153,356 is 30447612.
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 559 x 153 x 356 = 22257204372
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
559 : 1, 13, 43, 559
153 : 1, 3, 9, 17, 51, 153
356 : 1, 2, 4, 89, 178, 356
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,559,153,356, is 1.
Now, the common factors can be found like this.
731:17x 43
559:13x 43
153:3x 3x 17
356:2x 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.
17x 43 = 731
Therefore, the value for common factors is 731.
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 = 22257204372/(1x731)
LCM = 22257204372/731
LCM = 30447612
Thus, we can understand that the LCM of 731,559,153,356 is 30447612.
