Given numbers are 774,489,393,398

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

The LCM of 774,489,393,398 is 3288917178.

Find LCM of 774,489,393,398 with Prime Factorization

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

2 x 3 x 129 x 163 x 131 x 199 = 3288917178

Therefore, the lowest common multiple of 774,489,393,398 is 3288917178.

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.

774 x 489 x 393 x 398 = 59200509204

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.

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

489 : 1, 3, 163, 489

393 : 1, 3, 131, 393

398 : 1, 2, 199, 398

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,489,393,398, is 1.

Now, the common factors can be found like this.

774:2x 3x 3x 43

489:3x 163

393:3x 131

398:2x 199

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 59200509204/(1x18)

LCM = 59200509204/18

LCM = 3288917178

Thus, we can understand that the LCM of 774,489,393,398 is 3288917178.
