Given numbers are 826,387,865,771,942
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 826,387,865,771,942 is 11156806362870.
Find LCM of 826,387,865,771,942 with Prime Factorization
| 2 | 826, 387, 865, 771, 942 |
| 3 | 413, 387, 865, 771, 471 |
| 413, 129, 865, 257, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 413 x 129 x 865 x 257 x 157 = 11156806362870
Therefore, the lowest common multiple of 826,387,865,771,942 is 11156806362870.
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.
826 x 387 x 865 x 771 x 942 = 200822514531660
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.
826 : 1, 2, 7, 14, 59, 118, 413, 826
387 : 1, 3, 9, 43, 129, 387
865 : 1, 5, 173, 865
771 : 1, 3, 257, 771
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 826,387,865,771,942, is 1.
Now, the common factors can be found like this.
826:2x 7x 59
387:3x 3x 43
865:5x 173
771:3x 257
942:2x 3x 157
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 3 = 18
Therefore, the value for common factors is 18.
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 = 200822514531660/(1x18)
LCM = 200822514531660/18
LCM = 11156806362870
Thus, we can understand that the LCM of 826,387,865,771,942 is 11156806362870.
