Given numbers are 780,877,715,830,180

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

The LCM of 780,877,715,830,180 is 1873640340.

Find LCM of 780,877,715,830,180 with Prime Factorization

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

2 x 2 x 3 x 5 x 13 x 1 x 877 x 11 x 83 x 3 = 1873640340

Therefore, the lowest common multiple of 780,877,715,830,180 is 1873640340.

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 877 x 715 x 830 x 180 = 73071973260000

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

877 : 1, 877

715 : 1, 5, 11, 13, 55, 65, 143, 715

830 : 1, 2, 5, 10, 83, 166, 415, 830

180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,877,715,830,180, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

877:877

715:5x 11x 13

830:2x 5x 83

180:2x 2x 3x 3x 5

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 3x 5x 5x 5x 13 = 39000

Therefore, the value for common factors is 39000.

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 = 73071973260000/(1x39000)

LCM = 73071973260000/39000

LCM = 1873640340

Thus, we can understand that the LCM of 780,877,715,830,180 is 1873640340.
