Given numbers are 123,403,779,193,909
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 123,403,779,193,909 is 55076165469.
Find LCM of 123,403,779,193,909 with Prime Factorization
| 3 | 123, 403, 779, 193, 909 |
| 41 | 41, 403, 779, 193, 303 |
| 1, 403, 19, 193, 303 |
Multiply the prime numbers at the bottom and the left side.
3 x 41 x 1 x 403 x 19 x 193 x 303 = 55076165469
Therefore, the lowest common multiple of 123,403,779,193,909 is 55076165469.
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 403 x 779 x 193 x 909 = 6774368352687
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
403 : 1, 13, 31, 403
779 : 1, 19, 41, 779
193 : 1, 193
909 : 1, 3, 9, 101, 303, 909
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,403,779,193,909, is 1.
Now, the common factors can be found like this.
123:3x 41
403:13x 31
779:19x 41
193:193
909:3x 3x 101
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 41 = 123
Therefore, the value for common factors is 123.
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 = 6774368352687/(1x123)
LCM = 6774368352687/123
LCM = 55076165469
Thus, we can understand that the LCM of 123,403,779,193,909 is 55076165469.
