Given numbers are 920,805,856,654,439

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

The LCM of 920,805,856,654,439 is 98919501240.

Find LCM of 920,805,856,654,439 with Prime Factorization

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

2 x 2 x 2 x 5 x 23 x 1 x 7 x 107 x 327 x 439 = 98919501240

Therefore, the lowest common multiple of 920,805,856,654,439 is 98919501240.

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.

920 x 805 x 856 x 654 x 439 = 182011882281600

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.

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

805 : 1, 5, 7, 23, 35, 115, 161, 805

856 : 1, 2, 4, 8, 107, 214, 428, 856

654 : 1, 2, 3, 6, 109, 218, 327, 654

439 : 1, 439

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,805,856,654,439, is 1.

Now, the common factors can be found like this.

920:2x 2x 2x 5x 23

805:5x 7x 23

856:2x 2x 2x 107

654:2x 3x 109

439:439

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 23 = 1840

Therefore, the value for common factors is 1840.

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 = 182011882281600/(1x1840)

LCM = 182011882281600/1840

LCM = 98919501240

Thus, we can understand that the LCM of 920,805,856,654,439 is 98919501240.
