Given numbers are 280,571,780,802

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

The LCM of 280,571,780,802 is 2500363320.

Find LCM of 280,571,780,802 with Prime Factorization

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

2 x 2 x 5 x 14 x 571 x 39 x 401 = 2500363320

Therefore, the lowest common multiple of 280,571,780,802 is 2500363320.

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 571 x 780 x 802 = 100014532800

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

571 : 1, 571

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

802 : 1, 2, 401, 802

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,571,780,802, is 1.

Now, the common factors can be found like this.

280:2x 2x 2x 5x 7

571:571

780:2x 2x 3x 5x 13

802:2x 401

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 5 = 40

Therefore, the value for common factors is 40.

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 = 100014532800/(1x40)

LCM = 100014532800/40

LCM = 2500363320

Thus, we can understand that the LCM of 280,571,780,802 is 2500363320.
