Given numbers are 561,242,403,596,165
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,242,403,596,165 is 7411000740.
Find LCM of 561,242,403,596,165 with Prime Factorization
| 2 | 561, 242, 403, 596, 165 |
| 3 | 561, 121, 403, 298, 165 |
| 11 | 187, 121, 403, 298, 55 |
| 17, 11, 403, 298, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 17 x 11 x 403 x 298 x 5 = 7411000740
Therefore, the lowest common multiple of 561,242,403,596,165 is 7411000740.
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 242 x 403 x 596 x 165 = 5380386537240
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
242 : 1, 2, 11, 22, 121, 242
403 : 1, 13, 31, 403
596 : 1, 2, 4, 149, 298, 596
165 : 1, 3, 5, 11, 15, 33, 55, 165
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,242,403,596,165, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
242:2x 11x 11
403:13x 31
596:2x 2x 149
165:3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11x 11 = 726
Therefore, the value for common factors is 726.
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 = 5380386537240/(1x726)
LCM = 5380386537240/726
LCM = 7411000740
Thus, we can understand that the LCM of 561,242,403,596,165 is 7411000740.
