Given numbers are 161,528,103,711,865

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

The LCM of 161,528,103,711,865 is 1794987699120.

Find LCM of 161,528,103,711,865 with Prime Factorization

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

3 x 161 x 176 x 103 x 237 x 865 = 1794987699120

Therefore, the lowest common multiple of 161,528,103,711,865 is 1794987699120.

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 528 x 103 x 711 x 865 = 5384963097360

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

528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528

103 : 1, 103

711 : 1, 3, 9, 79, 237, 711

865 : 1, 5, 173, 865

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,528,103,711,865, is 1.

Now, the common factors can be found like this.

161:7x 23

528:2x 2x 2x 2x 3x 11

103:103

711:3x 3x 79

865:5x 173

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

3 = 3

Therefore, the value for common factors is 3.

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 = 5384963097360/(1x3)

LCM = 5384963097360/3

LCM = 1794987699120

Thus, we can understand that the LCM of 161,528,103,711,865 is 1794987699120.
