Given numbers are 640,190,270,580,281

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

The LCM of 640,190,270,580,281 is 2675479680.

Find LCM of 640,190,270,580,281 with Prime Factorization

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

2 x 2 x 5 x 32 x 19 x 27 x 29 x 281 = 2675479680

Therefore, the lowest common multiple of 640,190,270,580,281 is 2675479680.

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.

640 x 190 x 270 x 580 x 281 = 5350959360000

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.

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

190 : 1, 2, 5, 10, 19, 38, 95, 190

270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270

580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580

281 : 1, 281

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,190,270,580,281, is 1.

Now, the common factors can be found like this.

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

190:2x 5x 19

270:2x 3x 3x 3x 5

580:2x 2x 5x 29

281:281

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 5x 5x 5 = 2000

Therefore, the value for common factors is 2000.

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 = 5350959360000/(1x2000)

LCM = 5350959360000/2000

LCM = 2675479680

Thus, we can understand that the LCM of 640,190,270,580,281 is 2675479680.
