Given numbers are 805,780,286,710

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

The LCM of 805,780,286,710 is 98077980.

Find LCM of 805,780,286,710 with Prime Factorization

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

2 x 5 x 13 x 161 x 6 x 11 x 71 = 98077980

Therefore, the lowest common multiple of 805,780,286,710 is 98077980.

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.

805 x 780 x 286 x 710 = 127501374000

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.

805 : 1, 5, 7, 23, 35, 115, 161, 805

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

286 : 1, 2, 11, 13, 22, 26, 143, 286

710 : 1, 2, 5, 10, 71, 142, 355, 710

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 805,780,286,710, is 1.

Now, the common factors can be found like this.

805:5x 7x 23

780:2x 2x 3x 5x 13

286:2x 11x 13

710:2x 5x 71

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 5x 5x 13 = 1300

Therefore, the value for common factors is 1300.

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 = 127501374000/(1x1300)

LCM = 127501374000/1300

LCM = 98077980

Thus, we can understand that the LCM of 805,780,286,710 is 98077980.
