Given numbers are 803,221,233,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 803,221,233,561 is 124046637.
Find LCM of 803,221,233,561 with Prime Factorization
| 11 | 803, 221, 233, 561 |
| 17 | 73, 221, 233, 51 |
| 73, 13, 233, 3 |
Multiply the prime numbers at the bottom and the left side.
11 x 17 x 73 x 13 x 233 x 3 = 124046637
Therefore, the lowest common multiple of 803,221,233,561 is 124046637.
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.
803 x 221 x 233 x 561 = 23196721119
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.
803 : 1, 11, 73, 803
221 : 1, 13, 17, 221
233 : 1, 233
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 803,221,233,561, is 1.
Now, the common factors can be found like this.
803:11x 73
221:13x 17
233:233
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 17 = 187
Therefore, the value for common factors is 187.
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 = 23196721119/(1x187)
LCM = 23196721119/187
LCM = 124046637
Thus, we can understand that the LCM of 803,221,233,561 is 124046637.
