Given numbers are 338,653,640,170,867
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 338,653,640,170,867 is 61234892160.
Find LCM of 338,653,640,170,867 with Prime Factorization
| 2 | 338, 653, 640, 170, 867 |
| 5 | 169, 653, 320, 85, 867 |
| 17 | 169, 653, 64, 17, 867 |
| 169, 653, 64, 1, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 169 x 653 x 64 x 1 x 51 = 61234892160
Therefore, the lowest common multiple of 338,653,640,170,867 is 61234892160.
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.
338 x 653 x 640 x 170 x 867 = 20819863334400
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.
338 : 1, 2, 13, 26, 169, 338
653 : 1, 653
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
170 : 1, 2, 5, 10, 17, 34, 85, 170
867 : 1, 3, 17, 51, 289, 867
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,653,640,170,867, is 1.
Now, the common factors can be found like this.
338:2x 13x 13
653:653
640:2x 2x 2x 2x 2x 2x 2x 5
170:2x 5x 17
867:3x 17x 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 5x 17 = 340
Therefore, the value for common factors is 340.
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 = 20819863334400/(1x340)
LCM = 20819863334400/340
LCM = 61234892160
Thus, we can understand that the LCM of 338,653,640,170,867 is 61234892160.
