Given numbers are 123,902,989,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 123,902,989,621 is 24086106.
Find LCM of 123,902,989,621 with Prime Factorization
| 3 | 123, 902, 989, 621 |
| 23 | 41, 902, 989, 207 |
| 41 | 41, 902, 43, 9 |
| 1, 22, 43, 9 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 41 x 1 x 22 x 43 x 9 = 24086106
Therefore, the lowest common multiple of 123,902,989,621 is 24086106.
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.
123 x 902 x 989 x 621 = 68139593874
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.
123 : 1, 3, 41, 123
902 : 1, 2, 11, 22, 41, 82, 451, 902
989 : 1, 23, 43, 989
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,902,989,621, is 1.
Now, the common factors can be found like this.
123:3x 41
902:2x 11x 41
989:23x 43
621:3x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 23x 41 = 2829
Therefore, the value for common factors is 2829.
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 = 68139593874/(1x2829)
LCM = 68139593874/2829
LCM = 24086106
Thus, we can understand that the LCM of 123,902,989,621 is 24086106.
