Given numbers are 780,428,293,207

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

The LCM of 780,428,293,207 is 1687310820.

Find LCM of 780,428,293,207 with Prime Factorization

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

2 x 2 x 3 x 65 x 107 x 293 x 69 = 1687310820

Therefore, the lowest common multiple of 780,428,293,207 is 1687310820.

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 428 x 293 x 207 = 20247729840

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

428 : 1, 2, 4, 107, 214, 428

293 : 1, 293

207 : 1, 3, 9, 23, 69, 207

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,428,293,207, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

428:2x 2x 107

293:293

207:3x 3x 23

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 3 = 12

Therefore, the value for common factors is 12.

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 = 20247729840/(1x12)

LCM = 20247729840/12

LCM = 1687310820

Thus, we can understand that the LCM of 780,428,293,207 is 1687310820.
