Find LCM of 567,990,138,805,665 with Prime Factorization
| 2 | 567, 990, 138, 805, 665 |
| 3 | 567, 495, 69, 805, 665 |
| 3 | 189, 165, 23, 805, 665 |
| 5 | 63, 55, 23, 805, 665 |
| 7 | 63, 11, 23, 161, 133 |
| 23 | 9, 11, 23, 23, 19 |
| 9, 11, 1, 1, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 23 x 9 x 11 x 1 x 1 x 19 = 27255690
Therefore, the lowest common multiple of 567,990,138,805,665 is 27255690.
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 990 x 138 x 805 x 665 = 41468169550500
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
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
138 : 1, 2, 3, 6, 23, 46, 69, 138
805 : 1, 5, 7, 23, 35, 115, 161, 805
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 567,990,138,805,665, is 1.
Now, the common factors can be found like this.
567:3x 3x 3x 3x 7
990:2x 3x 3x 5x 11
138:2x 3x 23
805:5x 7x 23
665:5x 7x 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 3x 3x 3x 5x 5x 7x 7x 23 = 1521450
Therefore, the value for common factors is 1521450.
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 = 41468169550500/(1x1521450)
LCM = 41468169550500/1521450
LCM = 27255690
Thus, we can understand that the LCM of 567,990,138,805,665 is 27255690.
