Given numbers are 862,179,321,872
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 862,179,321,872 is 21594930888.
Find LCM of 862,179,321,872 with Prime Factorization
2 | 862, 179, 321, 872 |
431, 179, 321, 436 |
Multiply the prime numbers at the bottom and the left side.
2 x 431 x 179 x 321 x 436 = 21594930888
Therefore, the lowest common multiple of 862,179,321,872 is 21594930888.
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.
862 x 179 x 321 x 872 = 43189861776
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.
862 : 1, 2, 431, 862
179 : 1, 179
321 : 1, 3, 107, 321
872 : 1, 2, 4, 8, 109, 218, 436, 872
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,179,321,872, is 1.
Now, the common factors can be found like this.
862:2x 431
179:179
321:3x 107
872:2x 2x 2x 109
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 = 43189861776/(1x2)
LCM = 43189861776/2
LCM = 21594930888
Thus, we can understand that the LCM of 862,179,321,872 is 21594930888.
