Given numbers are 163,989,209,874

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

The LCM of 163,989,209,874 is 67384526.

Find LCM of 163,989,209,874 with Prime Factorization

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

19 x 23 x 163 x 43 x 11 x 2 = 67384526

Therefore, the lowest common multiple of 163,989,209,874 is 67384526.

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.

163 x 989 x 209 x 874 = 29447037862

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.

163 : 1, 163

989 : 1, 23, 43, 989

209 : 1, 11, 19, 209

874 : 1, 2, 19, 23, 38, 46, 437, 874

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,989,209,874, is 1.

Now, the common factors can be found like this.

163:163

989:23x 43

209:11x 19

874:2x 19x 23

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

19x 23 = 437

Therefore, the value for common factors is 437.

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 = 29447037862/(1x437)

LCM = 29447037862/437

LCM = 67384526

Thus, we can understand that the LCM of 163,989,209,874 is 67384526.
