Given numbers are 238,629,640,155,485
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 238,629,640,155,485 is 8473485440.
Find LCM of 238,629,640,155,485 with Prime Factorization
| 2 | 238, 629, 640, 155, 485 |
| 5 | 119, 629, 320, 155, 485 |
| 17 | 119, 629, 64, 31, 97 |
| 7, 37, 64, 31, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 7 x 37 x 64 x 31 x 97 = 8473485440
Therefore, the lowest common multiple of 238,629,640,155,485 is 8473485440.
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.
238 x 629 x 640 x 155 x 485 = 7202462624000
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.
238 : 1, 2, 7, 14, 17, 34, 119, 238
629 : 1, 17, 37, 629
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
155 : 1, 5, 31, 155
485 : 1, 5, 97, 485
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,629,640,155,485, is 1.
Now, the common factors can be found like this.
238:2x 7x 17
629:17x 37
640:2x 2x 2x 2x 2x 2x 2x 5
155:5x 31
485:5x 97
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 17 = 850
Therefore, the value for common factors is 850.
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 = 7202462624000/(1x850)
LCM = 7202462624000/850
LCM = 8473485440
Thus, we can understand that the LCM of 238,629,640,155,485 is 8473485440.
