Given numbers are 545,812,120,162
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 545,812,120,162 is 71691480.
Find LCM of 545,812,120,162 with Prime Factorization
| 2 | 545, 812, 120, 162 |
| 2 | 545, 406, 60, 81 |
| 3 | 545, 203, 30, 81 |
| 5 | 545, 203, 10, 27 |
| 109, 203, 2, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 109 x 203 x 2 x 27 = 71691480
Therefore, the lowest common multiple of 545,812,120,162 is 71691480.
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.
545 x 812 x 120 x 162 = 8602977600
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.
545 : 1, 5, 109, 545
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
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 545,812,120,162, is 1.
Now, the common factors can be found like this.
545:5x 109
812:2x 2x 7x 29
120:2x 2x 2x 3x 5
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 2x 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 8602977600/(1x120)
LCM = 8602977600/120
LCM = 71691480
Thus, we can understand that the LCM of 545,812,120,162 is 71691480.
