Given numbers are 238,756,490,544
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 238,756,490,544 is 3598560.
Find LCM of 238,756,490,544 with Prime Factorization
| 2 | 238, 756, 490, 544 |
| 2 | 119, 378, 245, 272 |
| 7 | 119, 189, 245, 136 |
| 17 | 17, 27, 35, 136 |
| 1, 27, 35, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 17 x 1 x 27 x 35 x 8 = 3598560
Therefore, the lowest common multiple of 238,756,490,544 is 3598560.
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.
238 x 756 x 490 x 544 = 47961607680
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.
238 : 1, 2, 7, 14, 17, 34, 119, 238
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,756,490,544, is 2.
Now, the common factors can be found like this.
238:2x 7x 17
756:2x 2x 3x 3x 3x 7
490:2x 5x 7x 7
544:2x 2x 2x 2x 2x 17
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 7x 7x 17 = 6664
Therefore, the value for common factors is 6664.
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 = 47961607680/(2x6664)
LCM = 47961607680/13328
LCM = 3598560
Thus, we can understand that the LCM of 238,756,490,544 is 3598560.
