Given numbers are 731,481,572,153
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 731,481,572,153 is 139237956.
Find LCM of 731,481,572,153 with Prime Factorization
| 13 | 731, 481, 572, 153 |
| 17 | 731, 37, 44, 153 |
| 43, 37, 44, 9 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 43 x 37 x 44 x 9 = 139237956
Therefore, the lowest common multiple of 731,481,572,153 is 139237956.
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 481 x 572 x 153 = 30771588276
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
481 : 1, 13, 37, 481
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
153 : 1, 3, 9, 17, 51, 153
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,481,572,153, is 1.
Now, the common factors can be found like this.
731:17x 43
481:13x 37
572:2x 2x 11x 13
153:3x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 17 = 221
Therefore, the value for common factors is 221.
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 = 30771588276/(1x221)
LCM = 30771588276/221
LCM = 139237956
Thus, we can understand that the LCM of 731,481,572,153 is 139237956.
