Given numbers are 137,162,921,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 137,162,921,686 is 2337050394.
Find LCM of 137,162,921,686 with Prime Factorization
| 2 | 137, 162, 921, 686 |
| 3 | 137, 81, 921, 343 |
| 137, 27, 307, 343 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 137 x 27 x 307 x 343 = 2337050394
Therefore, the lowest common multiple of 137,162,921,686 is 2337050394.
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.
137 x 162 x 921 x 686 = 14022302364
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.
137 : 1, 137
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
921 : 1, 3, 307, 921
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 137,162,921,686, is 1.
Now, the common factors can be found like this.
137:137
162:2x 3x 3x 3x 3
921:3x 307
686:2x 7x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 14022302364/(1x6)
LCM = 14022302364/6
LCM = 2337050394
Thus, we can understand that the LCM of 137,162,921,686 is 2337050394.
