Given numbers are 143,221,401,281

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 143,221,401,281 is 273927511.

Find LCM of 143,221,401,281 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

13 x 11 x 17 x 401 x 281 = 273927511

Therefore, the lowest common multiple of 143,221,401,281 is 273927511.

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.

143 x 221 x 401 x 281 = 3561057643

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.

143 : 1, 11, 13, 143

221 : 1, 13, 17, 221

401 : 1, 401

281 : 1, 281

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 143,221,401,281, is 1.

Now, the common factors can be found like this.

143:11x 13

221:13x 17

401:401

281:281

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

13 = 13

Therefore, the value for common factors is 13.

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 = 3561057643/(1x13)

LCM = 3561057643/13

LCM = 273927511

Thus, we can understand that the LCM of 143,221,401,281 is 273927511.
