Given numbers are 350,401,670,935,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 350,401,670,935,721 is 181119850450.
Find LCM of 350,401,670,935,721 with Prime Factorization
| 2 | 350, 401, 670, 935, 721 |
| 5 | 175, 401, 335, 935, 721 |
| 7 | 35, 401, 67, 187, 721 |
| 5, 401, 67, 187, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 5 x 401 x 67 x 187 x 103 = 181119850450
Therefore, the lowest common multiple of 350,401,670,935,721 is 181119850450.
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.
350 x 401 x 670 x 935 x 721 = 63391947657500
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.
350 : 1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350
401 : 1, 401
670 : 1, 2, 5, 10, 67, 134, 335, 670
935 : 1, 5, 11, 17, 55, 85, 187, 935
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 350,401,670,935,721, is 1.
Now, the common factors can be found like this.
350:2x 5x 5x 7
401:401
670:2x 5x 67
935:5x 11x 17
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.
2x 5x 5x 7 = 350
Therefore, the value for common factors is 350.
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 = 63391947657500/(1x350)
LCM = 63391947657500/350
LCM = 181119850450
Thus, we can understand that the LCM of 350,401,670,935,721 is 181119850450.
