Given numbers are 160,540,470,641

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

The LCM of 160,540,470,641 is 130148640.

Find LCM of 160,540,470,641 with Prime Factorization

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

2 x 2 x 5 x 8 x 27 x 47 x 641 = 130148640

Therefore, the lowest common multiple of 160,540,470,641 is 130148640.

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.

160 x 540 x 470 x 641 = 26029728000

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.

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540

470 : 1, 2, 5, 10, 47, 94, 235, 470

641 : 1, 641

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 160,540,470,641, is 1.

Now, the common factors can be found like this.

160:2x 2x 2x 2x 2x 5

540:2x 2x 3x 3x 3x 5

470:2x 5x 47

641:641

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 5x 5 = 200

Therefore, the value for common factors is 200.

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 = 26029728000/(1x200)

LCM = 26029728000/200

LCM = 130148640

Thus, we can understand that the LCM of 160,540,470,641 is 130148640.
