Given numbers are 249,730,657,171
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 249,730,657,171 is 10360890.
Find LCM of 249,730,657,171 with Prime Factorization
| 3 | 249, 730, 657, 171 |
| 3 | 83, 730, 219, 57 |
| 73 | 83, 730, 73, 19 |
| 83, 10, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 73 x 83 x 10 x 1 x 19 = 10360890
Therefore, the lowest common multiple of 249,730,657,171 is 10360890.
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.
249 x 730 x 657 x 171 = 20421314190
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.
249 : 1, 3, 83, 249
730 : 1, 2, 5, 10, 73, 146, 365, 730
657 : 1, 3, 9, 73, 219, 657
171 : 1, 3, 9, 19, 57, 171
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,730,657,171, is 1.
Now, the common factors can be found like this.
249:3x 83
730:2x 5x 73
657:3x 3x 73
171:3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 73 = 1971
Therefore, the value for common factors is 1971.
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 = 20421314190/(1x1971)
LCM = 20421314190/1971
LCM = 10360890
Thus, we can understand that the LCM of 249,730,657,171 is 10360890.
