Find LCM of 561,308,668,599,618 with Prime Factorization
| 2 | 561, 308, 668, 599, 618 |
| 2 | 561, 154, 334, 599, 309 |
| 3 | 561, 77, 167, 599, 309 |
| 11 | 187, 77, 167, 599, 103 |
| 17, 7, 167, 599, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 17 x 7 x 167 x 599 x 103 = 161845791492
Therefore, the lowest common multiple of 561,308,668,599,618 is 161845791492.
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.
561 x 308 x 668 x 599 x 618 = 42727288953888
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
668 : 1, 2, 4, 167, 334, 668
599 : 1, 599
618 : 1, 2, 3, 6, 103, 206, 309, 618
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,308,668,599,618, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
308:2x 2x 7x 11
668:2x 2x 167
599:599
618:2x 3x 103
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 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 42727288953888/(1x264)
LCM = 42727288953888/264
LCM = 161845791492
Thus, we can understand that the LCM of 561,308,668,599,618 is 161845791492.
