Given numbers are 281,201,176,638

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

The LCM of 281,201,176,638 is 288279024.

Find LCM of 281,201,176,638 with Prime Factorization

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

2 x 11 x 281 x 201 x 8 x 29 = 288279024

Therefore, the lowest common multiple of 281,201,176,638 is 288279024.

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.

281 x 201 x 176 x 638 = 6342138528

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.

281 : 1, 281

201 : 1, 3, 67, 201

176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,201,176,638, is 1.

Now, the common factors can be found like this.

281:281

201:3x 67

176:2x 2x 2x 2x 11

638:2x 11x 29

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 6342138528/(1x22)

LCM = 6342138528/22

LCM = 288279024

Thus, we can understand that the LCM of 281,201,176,638 is 288279024.
