Given numbers are 631,177,170,178

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

The LCM of 631,177,170,178 is 1689824310.

Find LCM of 631,177,170,178 with Prime Factorization

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

2 x 631 x 177 x 85 x 89 = 1689824310

Therefore, the lowest common multiple of 631,177,170,178 is 1689824310.

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.

631 x 177 x 170 x 178 = 3379648620

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.

631 : 1, 631

177 : 1, 3, 59, 177

170 : 1, 2, 5, 10, 17, 34, 85, 170

178 : 1, 2, 89, 178

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,177,170,178, is 1.

Now, the common factors can be found like this.

631:631

177:3x 59

170:2x 5x 17

178:2x 89

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

2 = 2

Therefore, the value for common factors is 2.

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 = 3379648620/(1x2)

LCM = 3379648620/2

LCM = 1689824310

Thus, we can understand that the LCM of 631,177,170,178 is 1689824310.

Here are some samples of LCM of two or more Numbers calculations.
