Given numbers are 536,660,644,161,857

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

The LCM of 536,660,644,161,857 is 12202685880.

Find LCM of 536,660,644,161,857 with Prime Factorization

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

2 x 2 x 7 x 23 x 134 x 165 x 1 x 1 x 857 = 12202685880

Therefore, the lowest common multiple of 536,660,644,161,857 is 12202685880.

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.

536 x 660 x 644 x 161 x 857 = 31434118826880

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.

536 : 1, 2, 4, 8, 67, 134, 268, 536

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

161 : 1, 7, 23, 161

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 536,660,644,161,857, is 1.

Now, the common factors can be found like this.

536:2x 2x 2x 67

660:2x 2x 3x 5x 11

644:2x 2x 7x 23

161:7x 23

857:857

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 2x 2x 7x 23 = 2576

Therefore, the value for common factors is 2576.

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 = 31434118826880/(1x2576)

LCM = 31434118826880/2576

LCM = 12202685880

Thus, we can understand that the LCM of 536,660,644,161,857 is 12202685880.
