Given numbers are 398,776,781,792

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

The LCM of 398,776,781,792 is 1085446296.

Find LCM of 398,776,781,792 with Prime Factorization

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

2 x 2 x 2 x 11 x 199 x 97 x 71 x 9 = 1085446296

Therefore, the lowest common multiple of 398,776,781,792 is 1085446296.

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.

398 x 776 x 781 x 792 = 191038548096

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.

398 : 1, 2, 199, 398

776 : 1, 2, 4, 8, 97, 194, 388, 776

781 : 1, 11, 71, 781

792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,776,781,792, is 1.

Now, the common factors can be found like this.

398:2x 199

776:2x 2x 2x 97

781:11x 71

792:2x 2x 2x 3x 3x 11

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 2x 11 = 176

Therefore, the value for common factors is 176.

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 = 191038548096/(1x176)

LCM = 191038548096/176

LCM = 1085446296

Thus, we can understand that the LCM of 398,776,781,792 is 1085446296.
