Given numbers are 161,538,392,730

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

The LCM of 161,538,392,730 is 885235960.

Find LCM of 161,538,392,730 with Prime Factorization

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

2 x 7 x 23 x 269 x 28 x 365 = 885235960

Therefore, the lowest common multiple of 161,538,392,730 is 885235960.

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 538 x 392 x 730 = 24786606880

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

538 : 1, 2, 269, 538

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

730 : 1, 2, 5, 10, 73, 146, 365, 730

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,538,392,730, is 1.

Now, the common factors can be found like this.

161:7x 23

538:2x 269

392:2x 2x 2x 7x 7

730:2x 5x 73

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 7 = 28

Therefore, the value for common factors is 28.

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 = 24786606880/(1x28)

LCM = 24786606880/28

LCM = 885235960

Thus, we can understand that the LCM of 161,538,392,730 is 885235960.
