Given numbers are 161,104,415,690

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

The LCM of 161,104,415,690 is 20846280.

Find LCM of 161,104,415,690 with Prime Factorization

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

2 x 5 x 23 x 7 x 52 x 83 x 3 = 20846280

Therefore, the lowest common multiple of 161,104,415,690 is 20846280.

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 104 x 415 x 690 = 4794644400

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

104 : 1, 2, 4, 8, 13, 26, 52, 104

415 : 1, 5, 83, 415

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,104,415,690, is 1.

Now, the common factors can be found like this.

161:7x 23

104:2x 2x 2x 13

415:5x 83

690:2x 3x 5x 23

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

2x 5x 23 = 230

Therefore, the value for common factors is 230.

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 = 4794644400/(1x230)

LCM = 4794644400/230

LCM = 20846280

Thus, we can understand that the LCM of 161,104,415,690 is 20846280.
