Given numbers are 418,441,694,686,170
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,441,694,686,170 is 38059345170.
Find LCM of 418,441,694,686,170 with Prime Factorization
| 2 | 418, 441, 694, 686, 170 |
| 7 | 209, 441, 347, 343, 85 |
| 7 | 209, 63, 347, 49, 85 |
| 209, 9, 347, 7, 85 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 209 x 9 x 347 x 7 x 85 = 38059345170
Therefore, the lowest common multiple of 418,441,694,686,170 is 38059345170.
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.
418 x 441 x 694 x 686 x 170 = 14919263306640
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
694 : 1, 2, 347, 694
686 : 1, 2, 7, 14, 49, 98, 343, 686
170 : 1, 2, 5, 10, 17, 34, 85, 170
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,441,694,686,170, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
441:3x 3x 7x 7
694:2x 347
686:2x 7x 7x 7
170:2x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 7x 7 = 392
Therefore, the value for common factors is 392.
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 = 14919263306640/(1x392)
LCM = 14919263306640/392
LCM = 38059345170
Thus, we can understand that the LCM of 418,441,694,686,170 is 38059345170.
