Given numbers are 238,842,415,546
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 238,842,415,546 is 1621704630.
Find LCM of 238,842,415,546 with Prime Factorization
| 2 | 238, 842, 415, 546 |
| 7 | 119, 421, 415, 273 |
| 17, 421, 415, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 17 x 421 x 415 x 39 = 1621704630
Therefore, the lowest common multiple of 238,842,415,546 is 1621704630.
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 842 x 415 x 546 = 45407729640
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
842 : 1, 2, 421, 842
415 : 1, 5, 83, 415
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 238,842,415,546, is 1.
Now, the common factors can be found like this.
238:2x 7x 17
842:2x 421
415:5x 83
546:2x 3x 7x 13
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 7 = 28
Therefore, the value for common factors is 28.
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 = 45407729640/(1x28)
LCM = 45407729640/28
LCM = 1621704630
Thus, we can understand that the LCM of 238,842,415,546 is 1621704630.
