Given numbers are 655,997,731,172,699
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,997,731,172,699 is 1334722563660.
Find LCM of 655,997,731,172,699 with Prime Factorization
| 43 | 655, 997, 731, 172, 699 |
| 655, 997, 17, 4, 699 |
Multiply the prime numbers at the bottom and the left side.
43 x 655 x 997 x 17 x 4 x 699 = 1334722563660
Therefore, the lowest common multiple of 655,997,731,172,699 is 1334722563660.
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.
655 x 997 x 731 x 172 x 699 = 57393070237380
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.
655 : 1, 5, 131, 655
997 : 1, 997
731 : 1, 17, 43, 731
172 : 1, 2, 4, 43, 86, 172
699 : 1, 3, 233, 699
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,997,731,172,699, is 1.
Now, the common factors can be found like this.
655:5x 131
997:997
731:17x 43
172:2x 2x 43
699:3x 233
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
43 = 43
Therefore, the value for common factors is 43.
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 = 57393070237380/(1x43)
LCM = 57393070237380/43
LCM = 1334722563660
Thus, we can understand that the LCM of 655,997,731,172,699 is 1334722563660.
