Given numbers are 492,997,812,690,842
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 492,997,812,690,842 is 4820990050380.
Find LCM of 492,997,812,690,842 with Prime Factorization
| 2 | 492, 997, 812, 690, 842 |
| 2 | 246, 997, 406, 345, 421 |
| 3 | 123, 997, 203, 345, 421 |
| 41, 997, 203, 115, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 41 x 997 x 203 x 115 x 421 = 4820990050380
Therefore, the lowest common multiple of 492,997,812,690,842 is 4820990050380.
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.
492 x 997 x 812 x 690 x 842 = 231407522418240
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.
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
997 : 1, 997
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 492,997,812,690,842, is 1.
Now, the common factors can be found like this.
492:2x 2x 3x 41
997:997
812:2x 2x 7x 29
690:2x 3x 5x 23
842:2x 421
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 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 231407522418240/(1x48)
LCM = 231407522418240/48
LCM = 4820990050380
Thus, we can understand that the LCM of 492,997,812,690,842 is 4820990050380.
