Given numbers are 675,394,128,785

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

The LCM of 675,394,128,785 is 2672265600.

Find LCM of 675,394,128,785 with Prime Factorization

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

2 x 5 x 135 x 197 x 64 x 157 = 2672265600

Therefore, the lowest common multiple of 675,394,128,785 is 2672265600.

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.

675 x 394 x 128 x 785 = 26722656000

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.

675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675

394 : 1, 2, 197, 394

128 : 1, 2, 4, 8, 16, 32, 64, 128

785 : 1, 5, 157, 785

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 675,394,128,785, is 1.

Now, the common factors can be found like this.

675:3x 3x 3x 5x 5

394:2x 197

128:2x 2x 2x 2x 2x 2x 2

785:5x 157

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 26722656000/(1x10)

LCM = 26722656000/10

LCM = 2672265600

Thus, we can understand that the LCM of 675,394,128,785 is 2672265600.
