Given numbers are 251,291,388,668
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 251,291,388,668 is 48791388.
Find LCM of 251,291,388,668 with Prime Factorization
| 2 | 251, 291, 388, 668 |
| 2 | 251, 291, 194, 334 |
| 97 | 251, 291, 97, 167 |
| 251, 3, 1, 167 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 97 x 251 x 3 x 1 x 167 = 48791388
Therefore, the lowest common multiple of 251,291,388,668 is 48791388.
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.
251 x 291 x 388 x 668 = 18931058544
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.
251 : 1, 251
291 : 1, 3, 97, 291
388 : 1, 2, 4, 97, 194, 388
668 : 1, 2, 4, 167, 334, 668
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,291,388,668, is 1.
Now, the common factors can be found like this.
251:251
291:3x 97
388:2x 2x 97
668:2x 2x 167
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 97 = 388
Therefore, the value for common factors is 388.
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 = 18931058544/(1x388)
LCM = 18931058544/388
LCM = 48791388
Thus, we can understand that the LCM of 251,291,388,668 is 48791388.
