Given numbers are 988,442,280,939,262
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 988,442,280,939,262 is 144624141480.
Find LCM of 988,442,280,939,262 with Prime Factorization
| 2 | 988, 442, 280, 939, 262 |
| 2 | 494, 221, 140, 939, 131 |
| 13 | 247, 221, 70, 939, 131 |
| 19, 17, 70, 939, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 19 x 17 x 70 x 939 x 131 = 144624141480
Therefore, the lowest common multiple of 988,442,280,939,262 is 144624141480.
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.
988 x 442 x 280 x 939 x 262 = 30081821427840
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.
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
442 : 1, 2, 13, 17, 26, 34, 221, 442
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
939 : 1, 3, 313, 939
262 : 1, 2, 131, 262
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,442,280,939,262, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
442:2x 13x 17
280:2x 2x 2x 5x 7
939:3x 313
262:2x 131
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 13 = 208
Therefore, the value for common factors is 208.
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 = 30081821427840/(1x208)
LCM = 30081821427840/208
LCM = 144624141480
Thus, we can understand that the LCM of 988,442,280,939,262 is 144624141480.
