Find LCM of 567,561,468,618,646 with Prime Factorization
| 2 | 567, 561, 468, 618, 646 |
| 3 | 567, 561, 234, 309, 323 |
| 3 | 189, 187, 78, 103, 323 |
| 17 | 63, 187, 26, 103, 323 |
| 63, 11, 26, 103, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 63 x 11 x 26 x 103 x 19 = 10789935156
Therefore, the lowest common multiple of 567,561,468,618,646 is 10789935156.
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.
567 x 561 x 468 x 618 x 646 = 59430962839248
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.
567 : 1, 3, 7, 9, 21, 27, 63, 81, 189, 567
561 : 1, 3, 11, 17, 33, 51, 187, 561
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
618 : 1, 2, 3, 6, 103, 206, 309, 618
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 567,561,468,618,646, is 1.
Now, the common factors can be found like this.
567:3x 3x 3x 3x 7
561:3x 11x 17
468:2x 2x 3x 3x 13
618:2x 3x 103
646:2x 17x 19
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 3x 3x 3x 3x 17 = 5508
Therefore, the value for common factors is 5508.
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 = 59430962839248/(1x5508)
LCM = 59430962839248/5508
LCM = 10789935156
Thus, we can understand that the LCM of 567,561,468,618,646 is 10789935156.
