Given numbers are 161,130,466,163,639

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

The LCM of 161,130,466,163,639 is 507941400330.

Find LCM of 161,130,466,163,639 with Prime Factorization

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

2 x 161 x 65 x 233 x 163 x 639 = 507941400330

Therefore, the lowest common multiple of 161,130,466,163,639 is 507941400330.

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 130 x 466 x 163 x 639 = 1015882800660

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

130 : 1, 2, 5, 10, 13, 26, 65, 130

466 : 1, 2, 233, 466

163 : 1, 163

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,130,466,163,639, is 1.

Now, the common factors can be found like this.

161:7x 23

130:2x 5x 13

466:2x 233

163:163

639:3x 3x 71

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

2 = 2

Therefore, the value for common factors is 2.

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 = 1015882800660/(1x2)

LCM = 1015882800660/2

LCM = 507941400330

Thus, we can understand that the LCM of 161,130,466,163,639 is 507941400330.
