Given numbers are 408,839,163,954,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 408,839,163,954,978 is 8871700104.
Find LCM of 408,839,163,954,978 with Prime Factorization
| 2 | 408, 839, 163, 954, 978 |
| 3 | 204, 839, 163, 477, 489 |
| 163 | 68, 839, 163, 159, 163 |
| 68, 839, 1, 159, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 163 x 68 x 839 x 1 x 159 x 1 = 8871700104
Therefore, the lowest common multiple of 408,839,163,954,978 is 8871700104.
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.
408 x 839 x 163 x 954 x 978 = 52059136210272
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
839 : 1, 839
163 : 1, 163
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,839,163,954,978, is 1.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
839:839
163:163
954:2x 3x 3x 53
978:2x 3x 163
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 3x 3x 163 = 5868
Therefore, the value for common factors is 5868.
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 = 52059136210272/(1x5868)
LCM = 52059136210272/5868
LCM = 8871700104
Thus, we can understand that the LCM of 408,839,163,954,978 is 8871700104.
