Given numbers are 780,866,578,572

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

The LCM of 780,866,578,572 is 1073675460.

Find LCM of 780,866,578,572 with Prime Factorization

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

2 x 2 x 13 x 15 x 433 x 289 x 11 = 1073675460

Therefore, the lowest common multiple of 780,866,578,572 is 1073675460.

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.

780 x 866 x 578 x 572 = 223324495680

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.

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

866 : 1, 2, 433, 866

578 : 1, 2, 17, 34, 289, 578

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,866,578,572, is 2.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

866:2x 433

578:2x 17x 17

572:2x 2x 11x 13

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 13 = 104

Therefore, the value for common factors is 104.

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 = 223324495680/(2x104)

LCM = 223324495680/208

LCM = 1073675460

Thus, we can understand that the LCM of 780,866,578,572 is 1073675460.
