Given numbers are 197,639,531,874
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 197,639,531,874 is 6491282778.
Find LCM of 197,639,531,874 with Prime Factorization
| 3 | 197, 639, 531, 874 |
| 3 | 197, 213, 177, 874 |
| 197, 71, 59, 874 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 197 x 71 x 59 x 874 = 6491282778
Therefore, the lowest common multiple of 197,639,531,874 is 6491282778.
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.
197 x 639 x 531 x 874 = 58421545002
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.
197 : 1, 197
639 : 1, 3, 9, 71, 213, 639
531 : 1, 3, 9, 59, 177, 531
874 : 1, 2, 19, 23, 38, 46, 437, 874
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 197,639,531,874, is 1.
Now, the common factors can be found like this.
197:197
639:3x 3x 71
531:3x 3x 59
874:2x 19x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 58421545002/(1x9)
LCM = 58421545002/9
LCM = 6491282778
Thus, we can understand that the LCM of 197,639,531,874 is 6491282778.
