Given numbers are 621,986,212,162
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 621,986,212,162 is 194713308.
Find LCM of 621,986,212,162 with Prime Factorization
2 | 621, 986, 212, 162 |
3 | 621, 493, 106, 81 |
3 | 207, 493, 106, 27 |
3 | 69, 493, 106, 9 |
23, 493, 106, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 23 x 493 x 106 x 3 = 194713308
Therefore, the lowest common multiple of 621,986,212,162 is 194713308.
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.
621 x 986 x 212 x 162 = 21029037264
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
986 : 1, 2, 17, 29, 34, 58, 493, 986
212 : 1, 2, 4, 53, 106, 212
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,986,212,162, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
986:2x 17x 29
212:2x 2x 53
162:2x 3x 3x 3x 3
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 21029037264/(1x108)
LCM = 21029037264/108
LCM = 194713308
Thus, we can understand that the LCM of 621,986,212,162 is 194713308.
