Given numbers are 638,968,794,718,303
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,968,794,718,303 is 1212274413768.
Find LCM of 638,968,794,718,303 with Prime Factorization
| 2 | 638, 968, 794, 718, 303 |
| 11 | 319, 484, 397, 359, 303 |
| 29, 44, 397, 359, 303 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 44 x 397 x 359 x 303 = 1212274413768
Therefore, the lowest common multiple of 638,968,794,718,303 is 1212274413768.
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.
638 x 968 x 794 x 718 x 303 = 106680148411584
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
794 : 1, 2, 397, 794
718 : 1, 2, 359, 718
303 : 1, 3, 101, 303
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,968,794,718,303, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
968:2x 2x 2x 11x 11
794:2x 397
718:2x 359
303:3x 101
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 11 = 88
Therefore, the value for common factors is 88.
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 = 106680148411584/(1x88)
LCM = 106680148411584/88
LCM = 1212274413768
Thus, we can understand that the LCM of 638,968,794,718,303 is 1212274413768.
