Given numbers are 161,532,209,460

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

The LCM of 161,532,209,460 is 672980.

Find LCM of 161,532,209,460 with Prime Factorization

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

2 x 2 x 7 x 19 x 23 x 1 x 1 x 11 x 5 = 672980

Therefore, the lowest common multiple of 161,532,209,460 is 672980.

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 532 x 209 x 460 = 8234583280

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

532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532

209 : 1, 11, 19, 209

460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,532,209,460, is 1.

Now, the common factors can be found like this.

161:7x 23

532:2x 2x 7x 19

209:11x 19

460:2x 2x 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 2x 7x 19x 23 = 12236

Therefore, the value for common factors is 12236.

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 = 8234583280/(1x12236)

LCM = 8234583280/12236

LCM = 672980

Thus, we can understand that the LCM of 161,532,209,460 is 672980.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 465, 600, 333, 612
