Given numbers are 741,169,612,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 741,169,612,731 is 84500676.
Find LCM of 741,169,612,731 with Prime Factorization
| 3 | 741, 169, 612, 731 |
| 13 | 247, 169, 204, 731 |
| 17 | 19, 13, 204, 731 |
| 19, 13, 12, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 17 x 19 x 13 x 12 x 43 = 84500676
Therefore, the lowest common multiple of 741,169,612,731 is 84500676.
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.
741 x 169 x 612 x 731 = 56023948188
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.
741 : 1, 3, 13, 19, 39, 57, 247, 741
169 : 1, 13, 169
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,169,612,731, is 1.
Now, the common factors can be found like this.
741:3x 13x 19
169:13x 13
612:2x 2x 3x 3x 17
731:17x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 17 = 663
Therefore, the value for common factors is 663.
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 = 56023948188/(1x663)
LCM = 56023948188/663
LCM = 84500676
Thus, we can understand that the LCM of 741,169,612,731 is 84500676.
