Given numbers are 203,521,418,168
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 203,521,418,168 is 530507208.
Find LCM of 203,521,418,168 with Prime Factorization
| 2 | 203, 521, 418, 168 |
| 7 | 203, 521, 209, 84 |
| 29, 521, 209, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 29 x 521 x 209 x 12 = 530507208
Therefore, the lowest common multiple of 203,521,418,168 is 530507208.
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.
203 x 521 x 418 x 168 = 7427100912
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.
203 : 1, 7, 29, 203
521 : 1, 521
418 : 1, 2, 11, 19, 22, 38, 209, 418
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 203,521,418,168, is 1.
Now, the common factors can be found like this.
203:7x 29
521:521
418:2x 11x 19
168:2x 2x 2x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 7427100912/(1x14)
LCM = 7427100912/14
LCM = 530507208
Thus, we can understand that the LCM of 203,521,418,168 is 530507208.
