Given numbers are 162,157,270,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 162,157,270,645 is 5468310.
Find LCM of 162,157,270,645 with Prime Factorization
2 | 162, 157, 270, 645 |
3 | 81, 157, 135, 645 |
3 | 27, 157, 45, 215 |
3 | 9, 157, 15, 215 |
5 | 3, 157, 5, 215 |
3, 157, 1, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 3 x 157 x 1 x 43 = 5468310
Therefore, the lowest common multiple of 162,157,270,645 is 5468310.
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.
162 x 157 x 270 x 645 = 4429331100
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.
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
157 : 1, 157
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 162,157,270,645, is 1.
Now, the common factors can be found like this.
162:2x 3x 3x 3x 3
157:157
270:2x 3x 3x 3x 5
645:3x 5x 43
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 3x 3x 3x 5 = 810
Therefore, the value for common factors is 810.
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 = 4429331100/(1x810)
LCM = 4429331100/810
LCM = 5468310
Thus, we can understand that the LCM of 162,157,270,645 is 5468310.
