Given numbers are 247,382,391,792,942
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 247,382,391,792,942 is 2293675163208.
Find LCM of 247,382,391,792,942 with Prime Factorization
| 2 | 247, 382, 391, 792, 942 |
| 3 | 247, 191, 391, 396, 471 |
| 247, 191, 391, 132, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 247 x 191 x 391 x 132 x 157 = 2293675163208
Therefore, the lowest common multiple of 247,382,391,792,942 is 2293675163208.
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.
247 x 382 x 391 x 792 x 942 = 27524101958496
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.
247 : 1, 13, 19, 247
382 : 1, 2, 191, 382
391 : 1, 17, 23, 391
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 247,382,391,792,942, is 1.
Now, the common factors can be found like this.
247:13x 19
382:2x 191
391:17x 23
792:2x 2x 2x 3x 3x 11
942:2x 3x 157
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 3 = 12
Therefore, the value for common factors is 12.
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 = 27524101958496/(1x12)
LCM = 27524101958496/12
LCM = 2293675163208
Thus, we can understand that the LCM of 247,382,391,792,942 is 2293675163208.
