Given numbers are 842,871,585,762
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 842,871,585,762 is 4191278130.
Find LCM of 842,871,585,762 with Prime Factorization
2 | 842, 871, 585, 762 |
3 | 421, 871, 585, 381 |
13 | 421, 871, 195, 127 |
421, 67, 15, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 421 x 67 x 15 x 127 = 4191278130
Therefore, the lowest common multiple of 842,871,585,762 is 4191278130.
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.
842 x 871 x 585 x 762 = 326919694140
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.
842 : 1, 2, 421, 842
871 : 1, 13, 67, 871
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
762 : 1, 2, 3, 6, 127, 254, 381, 762
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,871,585,762, is 1.
Now, the common factors can be found like this.
842:2x 421
871:13x 67
585:3x 3x 5x 13
762:2x 3x 127
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 13 = 78
Therefore, the value for common factors is 78.
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 = 326919694140/(1x78)
LCM = 326919694140/78
LCM = 4191278130
Thus, we can understand that the LCM of 842,871,585,762 is 4191278130.
