Given numbers are 261,406,251,203

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

The LCM of 261,406,251,203 is 917154.

Find LCM of 261,406,251,203 with Prime Factorization

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

7 x 29 x 9 x 2 x 251 x 1 = 917154

Therefore, the lowest common multiple of 261,406,251,203 is 917154.

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.

261 x 406 x 251 x 203 = 5399285598

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.

261 : 1, 3, 9, 29, 87, 261

406 : 1, 2, 7, 14, 29, 58, 203, 406

251 : 1, 251

203 : 1, 7, 29, 203

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,406,251,203, is 1.

Now, the common factors can be found like this.

261:3x 3x 29

406:2x 7x 29

251:251

203:7x 29

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

7x 29x 29 = 5887

Therefore, the value for common factors is 5887.

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 = 5399285598/(1x5887)

LCM = 5399285598/5887

LCM = 917154

Thus, we can understand that the LCM of 261,406,251,203 is 917154.
