Given numbers are 486,779,985,770
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 486,779,985,770 is 28714461930.
Find LCM of 486,779,985,770 with Prime Factorization
| 2 | 486, 779, 985, 770 |
| 5 | 243, 779, 985, 385 |
| 243, 779, 197, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 243 x 779 x 197 x 77 = 28714461930
Therefore, the lowest common multiple of 486,779,985,770 is 28714461930.
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.
486 x 779 x 985 x 770 = 287144619300
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.
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
779 : 1, 19, 41, 779
985 : 1, 5, 197, 985
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 486,779,985,770, is 1.
Now, the common factors can be found like this.
486:2x 3x 3x 3x 3x 3
779:19x 41
985:5x 197
770:2x 5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 287144619300/(1x10)
LCM = 287144619300/10
LCM = 28714461930
Thus, we can understand that the LCM of 486,779,985,770 is 28714461930.
