Find LCM of 923,297,990,220,878 with Prime Factorization
| 2 | 923, 297, 990, 220, 878 |
| 3 | 923, 297, 495, 110, 439 |
| 3 | 923, 99, 165, 110, 439 |
| 5 | 923, 33, 55, 110, 439 |
| 11 | 923, 33, 11, 22, 439 |
| 923, 3, 1, 2, 439 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 923 x 3 x 1 x 2 x 439 = 2406870180
Therefore, the lowest common multiple of 923,297,990,220,878 is 2406870180.
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.
923 x 297 x 990 x 220 x 878 = 52421632520400
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.
923 : 1, 13, 71, 923
297 : 1, 3, 9, 11, 27, 33, 99, 297
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
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
878 : 1, 2, 439, 878
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,297,990,220,878, is 1.
Now, the common factors can be found like this.
923:13x 71
297:3x 3x 3x 11
990:2x 3x 3x 5x 11
220:2x 2x 5x 11
878:2x 439
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 5x 11x 11 = 21780
Therefore, the value for common factors is 21780.
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 = 52421632520400/(1x21780)
LCM = 52421632520400/21780
LCM = 2406870180
Thus, we can understand that the LCM of 923,297,990,220,878 is 2406870180.
