Given numbers are 838,766,991,795,936
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,766,991,795,936 is 39446472644280.
Find LCM of 838,766,991,795,936 with Prime Factorization
| 2 | 838, 766, 991, 795, 936 |
| 3 | 419, 383, 991, 795, 468 |
| 419, 383, 991, 265, 156 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 419 x 383 x 991 x 265 x 156 = 39446472644280
Therefore, the lowest common multiple of 838,766,991,795,936 is 39446472644280.
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.
838 x 766 x 991 x 795 x 936 = 473357671731360
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.
838 : 1, 2, 419, 838
766 : 1, 2, 383, 766
991 : 1, 991
795 : 1, 3, 5, 15, 53, 159, 265, 795
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,766,991,795,936, is 1.
Now, the common factors can be found like this.
838:2x 419
766:2x 383
991:991
795:3x 5x 53
936:2x 2x 2x 3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3 = 12
Therefore, the value for common factors is 12.
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 = 473357671731360/(1x12)
LCM = 473357671731360/12
LCM = 39446472644280
Thus, we can understand that the LCM of 838,766,991,795,936 is 39446472644280.
