Given numbers are 443,221,143,493
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 443,221,143,493 is 31231057.
Find LCM of 443,221,143,493 with Prime Factorization
| 13 | 443, 221, 143, 493 |
| 17 | 443, 17, 11, 493 |
| 443, 1, 11, 29 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 443 x 1 x 11 x 29 = 31231057
Therefore, the lowest common multiple of 443,221,143,493 is 31231057.
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.
443 x 221 x 143 x 493 = 6902063597
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.
443 : 1, 443
221 : 1, 13, 17, 221
143 : 1, 11, 13, 143
493 : 1, 17, 29, 493
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 443,221,143,493, is 1.
Now, the common factors can be found like this.
443:443
221:13x 17
143:11x 13
493:17x 29
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 = 6902063597/(1x221)
LCM = 6902063597/221
LCM = 31231057
Thus, we can understand that the LCM of 443,221,143,493 is 31231057.
