Given numbers are 843,423,126,984
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,423,126,984 is 272909448.
Find LCM of 843,423,126,984 with Prime Factorization
| 2 | 843, 423, 126, 984 |
| 3 | 843, 423, 63, 492 |
| 3 | 281, 141, 21, 164 |
| 281, 47, 7, 164 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 281 x 47 x 7 x 164 = 272909448
Therefore, the lowest common multiple of 843,423,126,984 is 272909448.
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.
843 x 423 x 126 x 984 = 44211330576
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.
843 : 1, 3, 281, 843
423 : 1, 3, 9, 47, 141, 423
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,423,126,984, is 3.
Now, the common factors can be found like this.
843:3x 281
423:3x 3x 47
126:2x 3x 3x 7
984:2x 2x 2x 3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 44211330576/(3x54)
LCM = 44211330576/162
LCM = 272909448
Thus, we can understand that the LCM of 843,423,126,984 is 272909448.
