Given numbers are 867,221,169,433
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 867,221,169,433 is 63444459.
Find LCM of 867,221,169,433 with Prime Factorization
| 13 | 867, 221, 169, 433 |
| 17 | 867, 17, 13, 433 |
| 51, 1, 13, 433 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 51 x 1 x 13 x 433 = 63444459
Therefore, the lowest common multiple of 867,221,169,433 is 63444459.
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.
867 x 221 x 169 x 433 = 14021225439
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.
867 : 1, 3, 17, 51, 289, 867
221 : 1, 13, 17, 221
169 : 1, 13, 169
433 : 1, 433
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,221,169,433, is 1.
Now, the common factors can be found like this.
867:3x 17x 17
221:13x 17
169:13x 13
433:433
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 17 = 221
Therefore, the value for common factors is 221.
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 = 14021225439/(1x221)
LCM = 14021225439/221
LCM = 63444459
Thus, we can understand that the LCM of 867,221,169,433 is 63444459.
