Given numbers are 631,172,387,946

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

The LCM of 631,172,387,946 is 10744668.

Find LCM of 631,172,387,946 with Prime Factorization

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

2 x 43 x 631 x 2 x 9 x 11 = 10744668

Therefore, the lowest common multiple of 631,172,387,946 is 10744668.

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 172 x 387 x 946 = 39733782264

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

172 : 1, 2, 4, 43, 86, 172

387 : 1, 3, 9, 43, 129, 387

946 : 1, 2, 11, 22, 43, 86, 473, 946

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,172,387,946, is 1.

Now, the common factors can be found like this.

631:631

172:2x 2x 43

387:3x 3x 43

946:2x 11x 43

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

2x 43x 43 = 3698

Therefore, the value for common factors is 3698.

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 = 39733782264/(1x3698)

LCM = 39733782264/3698

LCM = 10744668

Thus, we can understand that the LCM of 631,172,387,946 is 10744668.
