Given numbers are 320,640,326,485,137

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

The LCM of 320,640,326,485,137 is 1386308480.

Find LCM of 320,640,326,485,137 with Prime Factorization

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

2 x 2 x 2 x 2 x 2 x 2 x 5 x 1 x 2 x 163 x 97 x 137 = 1386308480

Therefore, the lowest common multiple of 320,640,326,485,137 is 1386308480.

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.

320 x 640 x 326 x 485 x 137 = 4436187136000

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.

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

326 : 1, 2, 163, 326

485 : 1, 5, 97, 485

137 : 1, 137

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 320,640,326,485,137, is 1.

Now, the common factors can be found like this.

320:2x 2x 2x 2x 2x 2x 5

640:2x 2x 2x 2x 2x 2x 2x 5

326:2x 163

485:5x 97

137:137

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 2x 2x 2x 5x 5 = 3200

Therefore, the value for common factors is 3200.

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 = 4436187136000/(1x3200)

LCM = 4436187136000/3200

LCM = 1386308480

Thus, we can understand that the LCM of 320,640,326,485,137 is 1386308480.
