Given numbers are 397,870,780,702

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

The LCM of 397,870,780,702 is 80821260.

Find LCM of 397,870,780,702 with Prime Factorization

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

2 x 3 x 5 x 13 x 397 x 29 x 2 x 9 = 80821260

Therefore, the lowest common multiple of 397,870,780,702 is 80821260.

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.

397 x 870 x 780 x 702 = 189121748400

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.

397 : 1, 397

870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870

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

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,870,780,702, is 1.

Now, the common factors can be found like this.

397:397

870:2x 3x 5x 29

780:2x 2x 3x 5x 13

702:2x 3x 3x 3x 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 3x 3x 5x 13 = 2340

Therefore, the value for common factors is 2340.

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 = 189121748400/(1x2340)

LCM = 189121748400/2340

LCM = 80821260

Thus, we can understand that the LCM of 397,870,780,702 is 80821260.
