Given numbers are 843,786,959,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,786,959,931 is 28170795702.
Find LCM of 843,786,959,931 with Prime Factorization
| 3 | 843, 786, 959, 931 |
| 7 | 281, 262, 959, 931 |
| 281, 262, 137, 133 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 281 x 262 x 137 x 133 = 28170795702
Therefore, the lowest common multiple of 843,786,959,931 is 28170795702.
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.
843 x 786 x 959 x 931 = 591586709742
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.
843 : 1, 3, 281, 843
786 : 1, 2, 3, 6, 131, 262, 393, 786
959 : 1, 7, 137, 959
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,786,959,931, is 1.
Now, the common factors can be found like this.
843:3x 281
786:2x 3x 131
959:7x 137
931:7x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 591586709742/(1x21)
LCM = 591586709742/21
LCM = 28170795702
Thus, we can understand that the LCM of 843,786,959,931 is 28170795702.
