Given numbers are 221,321,418,250
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 221,321,418,250 is 3706667250.
Find LCM of 221,321,418,250 with Prime Factorization
| 2 | 221, 321, 418, 250 |
| 221, 321, 209, 125 |
Multiply the prime numbers at the bottom and the left side.
2 x 221 x 321 x 209 x 125 = 3706667250
Therefore, the lowest common multiple of 221,321,418,250 is 3706667250.
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.
221 x 321 x 418 x 250 = 7413334500
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.
221 : 1, 13, 17, 221
321 : 1, 3, 107, 321
418 : 1, 2, 11, 19, 22, 38, 209, 418
250 : 1, 2, 5, 10, 25, 50, 125, 250
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,321,418,250, is 1.
Now, the common factors can be found like this.
221:13x 17
321:3x 107
418:2x 11x 19
250:2x 5x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 7413334500/(1x2)
LCM = 7413334500/2
LCM = 3706667250
Thus, we can understand that the LCM of 221,321,418,250 is 3706667250.
