Given numbers are 531,724,198,991
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 531,724,198,991 is 4190824044.
Find LCM of 531,724,198,991 with Prime Factorization
| 2 | 531, 724, 198, 991 |
| 3 | 531, 362, 99, 991 |
| 3 | 177, 362, 33, 991 |
| 59, 362, 11, 991 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 59 x 362 x 11 x 991 = 4190824044
Therefore, the lowest common multiple of 531,724,198,991 is 4190824044.
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.
531 x 724 x 198 x 991 = 75434832792
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.
531 : 1, 3, 9, 59, 177, 531
724 : 1, 2, 4, 181, 362, 724
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 531,724,198,991, is 1.
Now, the common factors can be found like this.
531:3x 3x 59
724:2x 2x 181
198:2x 3x 3x 11
991:991
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 3 = 18
Therefore, the value for common factors is 18.
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 = 75434832792/(1x18)
LCM = 75434832792/18
LCM = 4190824044
Thus, we can understand that the LCM of 531,724,198,991 is 4190824044.
