Given numbers are 273,181,140,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 273,181,140,644 is 22729980.
Find LCM of 273,181,140,644 with Prime Factorization
| 2 | 273, 181, 140, 644 |
| 2 | 273, 181, 70, 322 |
| 7 | 273, 181, 35, 161 |
| 39, 181, 5, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 39 x 181 x 5 x 23 = 22729980
Therefore, the lowest common multiple of 273,181,140,644 is 22729980.
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.
273 x 181 x 140 x 644 = 4455076080
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.
273 : 1, 3, 7, 13, 21, 39, 91, 273
181 : 1, 181
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 273,181,140,644, is 1.
Now, the common factors can be found like this.
273:3x 7x 13
181:181
140:2x 2x 5x 7
644:2x 2x 7x 23
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 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 4455076080/(1x196)
LCM = 4455076080/196
LCM = 22729980
Thus, we can understand that the LCM of 273,181,140,644 is 22729980.
