Given numbers are 281,822,392,985
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 281,822,392,985 is 44593384920.
Find LCM of 281,822,392,985 with Prime Factorization
| 2 | 281, 822, 392, 985 |
| 281, 411, 196, 985 |
Multiply the prime numbers at the bottom and the left side.
2 x 281 x 411 x 196 x 985 = 44593384920
Therefore, the lowest common multiple of 281,822,392,985 is 44593384920.
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.
281 x 822 x 392 x 985 = 89186769840
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.
281 : 1, 281
822 : 1, 2, 3, 6, 137, 274, 411, 822
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
985 : 1, 5, 197, 985
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,822,392,985, is 1.
Now, the common factors can be found like this.
281:281
822:2x 3x 137
392:2x 2x 2x 7x 7
985:5x 197
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 89186769840/(1x2)
LCM = 89186769840/2
LCM = 44593384920
Thus, we can understand that the LCM of 281,822,392,985 is 44593384920.
