Given numbers are 280,780,127,855,145

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

The LCM of 280,780,127,855,145 is 2292446520.

Find LCM of 280,780,127,855,145 with Prime Factorization

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

2 x 2 x 3 x 5 x 14 x 13 x 127 x 57 x 29 = 2292446520

Therefore, the lowest common multiple of 280,780,127,855,145 is 2292446520.

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 780 x 127 x 855 x 145 = 3438669780000

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

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

127 : 1, 127

855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855

145 : 1, 5, 29, 145

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,780,127,855,145, is 1.

Now, the common factors can be found like this.

280:2x 2x 2x 5x 7

780:2x 2x 3x 5x 13

127:127

855:3x 3x 5x 19

145:5x 29

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 3x 5x 5x 5 = 1500

Therefore, the value for common factors is 1500.

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 = 3438669780000/(1x1500)

LCM = 3438669780000/1500

LCM = 2292446520

Thus, we can understand that the LCM of 280,780,127,855,145 is 2292446520.
