Given numbers are 861,782,199,668

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

The LCM of 861,782,199,668 is 44751690732.

Find LCM of 861,782,199,668 with Prime Factorization

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

2 x 861 x 391 x 199 x 334 = 44751690732

Therefore, the lowest common multiple of 861,782,199,668 is 44751690732.

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.

861 x 782 x 199 x 668 = 89503381464

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

782 : 1, 2, 17, 23, 34, 46, 391, 782

199 : 1, 199

668 : 1, 2, 4, 167, 334, 668

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,782,199,668, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

782:2x 17x 23

199:199

668:2x 2x 167

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 = 89503381464/(1x2)

LCM = 89503381464/2

LCM = 44751690732

Thus, we can understand that the LCM of 861,782,199,668 is 44751690732.
