Given numbers are 170,401,697,615,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 170,401,697,615,721 is 6045520110.
Find LCM of 170,401,697,615,721 with Prime Factorization
| 5 | 170, 401, 697, 615, 721 |
| 17 | 34, 401, 697, 123, 721 |
| 41 | 2, 401, 41, 123, 721 |
| 2, 401, 1, 3, 721 |
Multiply the prime numbers at the bottom and the left side.
5 x 17 x 41 x 2 x 401 x 1 x 3 x 721 = 6045520110
Therefore, the lowest common multiple of 170,401,697,615,721 is 6045520110.
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.
170 x 401 x 697 x 615 x 721 = 21068637583350
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.
170 : 1, 2, 5, 10, 17, 34, 85, 170
401 : 1, 401
697 : 1, 17, 41, 697
615 : 1, 3, 5, 15, 41, 123, 205, 615
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 170,401,697,615,721, is 1.
Now, the common factors can be found like this.
170:2x 5x 17
401:401
697:17x 41
615:3x 5x 41
721:7x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 17x 41 = 3485
Therefore, the value for common factors is 3485.
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 = 21068637583350/(1x3485)
LCM = 21068637583350/3485
LCM = 6045520110
Thus, we can understand that the LCM of 170,401,697,615,721 is 6045520110.
