Given numbers are 403,780,933,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,780,933,961 is 233119380.
Find LCM of 403,780,933,961 with Prime Factorization
3 | 403, 780, 933, 961 |
13 | 403, 260, 311, 961 |
31 | 31, 20, 311, 961 |
1, 20, 311, 31 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 31 x 1 x 20 x 311 x 31 = 233119380
Therefore, the lowest common multiple of 403,780,933,961 is 233119380.
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.
403 x 780 x 933 x 961 = 281841330420
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.
403 : 1, 13, 31, 403
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
933 : 1, 3, 311, 933
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,780,933,961, is 1.
Now, the common factors can be found like this.
403:13x 31
780:2x 2x 3x 5x 13
933:3x 311
961:31x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 31 = 1209
Therefore, the value for common factors is 1209.
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 = 281841330420/(1x1209)
LCM = 281841330420/1209
LCM = 233119380
Thus, we can understand that the LCM of 403,780,933,961 is 233119380.
