Given numbers are 838,391,334,771
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,391,334,771 is 42188261106.
Find LCM of 838,391,334,771 with Prime Factorization
| 2 | 838, 391, 334, 771 |
| 419, 391, 167, 771 |
Multiply the prime numbers at the bottom and the left side.
2 x 419 x 391 x 167 x 771 = 42188261106
Therefore, the lowest common multiple of 838,391,334,771 is 42188261106.
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 391 x 334 x 771 = 84376522212
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
391 : 1, 17, 23, 391
334 : 1, 2, 167, 334
771 : 1, 3, 257, 771
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,391,334,771, is 1.
Now, the common factors can be found like this.
838:2x 419
391:17x 23
334:2x 167
771:3x 257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 84376522212/(1x2)
LCM = 84376522212/2
LCM = 42188261106
Thus, we can understand that the LCM of 838,391,334,771 is 42188261106.
