Given numbers are 836,284,397,860
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 836,284,397,860 is 5066331380.
Find LCM of 836,284,397,860 with Prime Factorization
| 2 | 836, 284, 397, 860 |
| 2 | 418, 142, 397, 430 |
| 209, 71, 397, 215 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 209 x 71 x 397 x 215 = 5066331380
Therefore, the lowest common multiple of 836,284,397,860 is 5066331380.
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.
836 x 284 x 397 x 860 = 81061302080
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.
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
284 : 1, 2, 4, 71, 142, 284
397 : 1, 397
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,284,397,860, is 1.
Now, the common factors can be found like this.
836:2x 2x 11x 19
284:2x 2x 71
397:397
860:2x 2x 5x 43
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 2x 2 = 16
Therefore, the value for common factors is 16.
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 = 81061302080/(1x16)
LCM = 81061302080/16
LCM = 5066331380
Thus, we can understand that the LCM of 836,284,397,860 is 5066331380.
