Given numbers are 409,247,403,243
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 409,247,403,243 is 761006259.
Find LCM of 409,247,403,243 with Prime Factorization
| 13 | 409, 247, 403, 243 |
| 409, 19, 31, 243 |
Multiply the prime numbers at the bottom and the left side.
13 x 409 x 19 x 31 x 243 = 761006259
Therefore, the lowest common multiple of 409,247,403,243 is 761006259.
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.
409 x 247 x 403 x 243 = 9893081367
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.
409 : 1, 409
247 : 1, 13, 19, 247
403 : 1, 13, 31, 403
243 : 1, 3, 9, 27, 81, 243
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,247,403,243, is 1.
Now, the common factors can be found like this.
409:409
247:13x 19
403:13x 31
243:3x 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.
13 = 13
Therefore, the value for common factors is 13.
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 = 9893081367/(1x13)
LCM = 9893081367/13
LCM = 761006259
Thus, we can understand that the LCM of 409,247,403,243 is 761006259.
