Given numbers are 261,256,319,657
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 261,256,319,657 is 53653248.
Find LCM of 261,256,319,657 with Prime Factorization
| 3 | 261, 256, 319, 657 |
| 3 | 87, 256, 319, 219 |
| 29 | 29, 256, 319, 73 |
| 1, 256, 11, 73 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 29 x 1 x 256 x 11 x 73 = 53653248
Therefore, the lowest common multiple of 261,256,319,657 is 53653248.
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.
261 x 256 x 319 x 657 = 14003497728
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.
261 : 1, 3, 9, 29, 87, 261
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
319 : 1, 11, 29, 319
657 : 1, 3, 9, 73, 219, 657
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,256,319,657, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
256:2x 2x 2x 2x 2x 2x 2x 2
319:11x 29
657:3x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 29 = 261
Therefore, the value for common factors is 261.
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 = 14003497728/(1x261)
LCM = 14003497728/261
LCM = 53653248
Thus, we can understand that the LCM of 261,256,319,657 is 53653248.
