Given numbers are 772,780,442,283

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

The LCM of 772,780,442,283 is 724247940.

Find LCM of 772,780,442,283 with Prime Factorization

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

2 x 2 x 13 x 193 x 15 x 17 x 283 = 724247940

Therefore, the lowest common multiple of 772,780,442,283 is 724247940.

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.

772 x 780 x 442 x 283 = 75321785760

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.

772 : 1, 2, 4, 193, 386, 772

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

442 : 1, 2, 13, 17, 26, 34, 221, 442

283 : 1, 283

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,780,442,283, is 1.

Now, the common factors can be found like this.

772:2x 2x 193

780:2x 2x 3x 5x 13

442:2x 13x 17

283:283

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 = 75321785760/(1x104)

LCM = 75321785760/104

LCM = 724247940

Thus, we can understand that the LCM of 772,780,442,283 is 724247940.
