Given numbers are 989,310,161,729

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

The LCM of 989,310,161,729 is 1564528770.

Find LCM of 989,310,161,729 with Prime Factorization

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

23 x 43 x 310 x 7 x 729 = 1564528770

Therefore, the lowest common multiple of 989,310,161,729 is 1564528770.

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.

989 x 310 x 161 x 729 = 35984161710

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.

989 : 1, 23, 43, 989

310 : 1, 2, 5, 10, 31, 62, 155, 310

161 : 1, 7, 23, 161

729 : 1, 3, 9, 27, 81, 243, 729

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,310,161,729, is 1.

Now, the common factors can be found like this.

989:23x 43

310:2x 5x 31

161:7x 23

729:3x 3x 3x 3x 3x 3

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

23 = 23

Therefore, the value for common factors is 23.

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 = 35984161710/(1x23)

LCM = 35984161710/23

LCM = 1564528770

Thus, we can understand that the LCM of 989,310,161,729 is 1564528770.
