The LCM of 264,920,621,661 is 180611640.
Find LCM of 264,920,621,661 with Prime Factorization
| 2 | 264, 920, 621, 661 |
| 2 | 132, 460, 621, 661 |
| 2 | 66, 230, 621, 661 |
| 3 | 33, 115, 621, 661 |
| 23 | 11, 115, 207, 661 |
| 11, 5, 9, 661 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 23 x 11 x 5 x 9 x 661 = 180611640
Therefore, the lowest common multiple of 264,920,621,661 is 180611640.
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.
264 x 920 x 621 x 661 = 99697625280
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.
264 : 1, 2, 3, 4, 6, 8, 11, 12, 22, 24, 33, 44, 66, 88, 132, 264
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
621 : 1, 3, 9, 23, 27, 69, 207, 621
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 264,920,621,661, is 1.
Now, the common factors can be found like this.
264:2x 2x 2x 3x 11
920:2x 2x 2x 5x 23
621:3x 3x 3x 23
661:661
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 23 = 552
Therefore, the value for common factors is 552.
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 = 99697625280/(1x552)
LCM = 99697625280/552
LCM = 180611640
Thus, we can understand that the LCM of 264,920,621,661 is 180611640.
