Given numbers are 280,894,818,545

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

The LCM of 280,894,818,545 is 5579757960.

Find LCM of 280,894,818,545 with Prime Factorization

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

2 x 5 x 28 x 447 x 409 x 109 = 5579757960

Therefore, the lowest common multiple of 280,894,818,545 is 5579757960.

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.

280 x 894 x 818 x 545 = 111595159200

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.

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

894 : 1, 2, 3, 6, 149, 298, 447, 894

818 : 1, 2, 409, 818

545 : 1, 5, 109, 545

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,894,818,545, is 1.

Now, the common factors can be found like this.

280:2x 2x 2x 5x 7

894:2x 3x 149

818:2x 409

545:5x 109

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 5 = 20

Therefore, the value for common factors is 20.

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 = 111595159200/(1x20)

LCM = 111595159200/20

LCM = 5579757960

Thus, we can understand that the LCM of 280,894,818,545 is 5579757960.
