Given numbers are 342,779,722,915
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 342,779,722,915 is 81257490.
Find LCM of 342,779,722,915 with Prime Factorization
| 2 | 342, 779, 722, 915 |
| 3 | 171, 779, 361, 915 |
| 19 | 57, 779, 361, 305 |
| 3, 41, 19, 305 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 3 x 41 x 19 x 305 = 81257490
Therefore, the lowest common multiple of 342,779,722,915 is 81257490.
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.
342 x 779 x 722 x 915 = 176003723340
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.
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
779 : 1, 19, 41, 779
722 : 1, 2, 19, 38, 361, 722
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 342,779,722,915, is 1.
Now, the common factors can be found like this.
342:2x 3x 3x 19
779:19x 41
722:2x 19x 19
915:3x 5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 19x 19 = 2166
Therefore, the value for common factors is 2166.
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 = 176003723340/(1x2166)
LCM = 176003723340/2166
LCM = 81257490
Thus, we can understand that the LCM of 342,779,722,915 is 81257490.
