Given numbers are 861,803,652,163

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

The LCM of 861,803,652,163 is 450781716.

Find LCM of 861,803,652,163 with Prime Factorization

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

163 x 861 x 803 x 4 x 1 = 450781716

Therefore, the lowest common multiple of 861,803,652,163 is 450781716.

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 803 x 652 x 163 = 73477419708

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

803 : 1, 11, 73, 803

652 : 1, 2, 4, 163, 326, 652

163 : 1, 163

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,803,652,163, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

803:11x 73

652:2x 2x 163

163:163

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

163 = 163

Therefore, the value for common factors is 163.

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 = 73477419708/(1x163)

LCM = 73477419708/163

LCM = 450781716

Thus, we can understand that the LCM of 861,803,652,163 is 450781716.
