Given numbers are 749,221,731,135
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,221,731,135 is 960895845.
Find LCM of 749,221,731,135 with Prime Factorization
| 17 | 749, 221, 731, 135 |
| 749, 13, 43, 135 |
Multiply the prime numbers at the bottom and the left side.
17 x 749 x 13 x 43 x 135 = 960895845
Therefore, the lowest common multiple of 749,221,731,135 is 960895845.
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.
749 x 221 x 731 x 135 = 16335229365
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.
749 : 1, 7, 107, 749
221 : 1, 13, 17, 221
731 : 1, 17, 43, 731
135 : 1, 3, 5, 9, 15, 27, 45, 135
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,221,731,135, is 1.
Now, the common factors can be found like this.
749:7x 107
221:13x 17
731:17x 43
135:3x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17 = 17
Therefore, the value for common factors is 17.
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 = 16335229365/(1x17)
LCM = 16335229365/17
LCM = 960895845
Thus, we can understand that the LCM of 749,221,731,135 is 960895845.
