Given numbers are 647,874,231,549
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,874,231,549 is 23904451494.
Find LCM of 647,874,231,549 with Prime Factorization
| 3 | 647, 874, 231, 549 |
| 647, 874, 77, 183 |
Multiply the prime numbers at the bottom and the left side.
3 x 647 x 874 x 77 x 183 = 23904451494
Therefore, the lowest common multiple of 647,874,231,549 is 23904451494.
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.
647 x 874 x 231 x 549 = 71713354482
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.
647 : 1, 647
874 : 1, 2, 19, 23, 38, 46, 437, 874
231 : 1, 3, 7, 11, 21, 33, 77, 231
549 : 1, 3, 9, 61, 183, 549
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,874,231,549, is 1.
Now, the common factors can be found like this.
647:647
874:2x 19x 23
231:3x 7x 11
549:3x 3x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 71713354482/(1x3)
LCM = 71713354482/3
LCM = 23904451494
Thus, we can understand that the LCM of 647,874,231,549 is 23904451494.
