Given numbers are 161,742,204,997

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

The LCM of 161,742,204,997 is 1735509804.

Find LCM of 161,742,204,997 with Prime Factorization

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

2 x 7 x 23 x 53 x 102 x 997 = 1735509804

Therefore, the lowest common multiple of 161,742,204,997 is 1735509804.

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.

161 x 742 x 204 x 997 = 24297137256

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.

161 : 1, 7, 23, 161

742 : 1, 2, 7, 14, 53, 106, 371, 742

204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204

997 : 1, 997

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,742,204,997, is 1.

Now, the common factors can be found like this.

161:7x 23

742:2x 7x 53

204:2x 2x 3x 17

997:997

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 24297137256/(1x14)

LCM = 24297137256/14

LCM = 1735509804

Thus, we can understand that the LCM of 161,742,204,997 is 1735509804.
