Given numbers are 281,230,140,698

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

The LCM of 281,230,140,698 is 315782180.

Find LCM of 281,230,140,698 with Prime Factorization

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

2 x 5 x 281 x 23 x 14 x 349 = 315782180

Therefore, the lowest common multiple of 281,230,140,698 is 315782180.

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 230 x 140 x 698 = 6315643600

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

230 : 1, 2, 5, 10, 23, 46, 115, 230

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

698 : 1, 2, 349, 698

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 281,230,140,698, is 1.

Now, the common factors can be found like this.

281:281

230:2x 5x 23

140:2x 2x 5x 7

698:2x 349

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

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 6315643600/(1x20)

LCM = 6315643600/20

LCM = 315782180

Thus, we can understand that the LCM of 281,230,140,698 is 315782180.
