Given numbers are 402,787,646,194

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

The LCM of 402,787,646,194 is 9912313794.

Find LCM of 402,787,646,194 with Prime Factorization

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

2 x 201 x 787 x 323 x 97 = 9912313794

Therefore, the lowest common multiple of 402,787,646,194 is 9912313794.

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.

402 x 787 x 646 x 194 = 39649255176

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.

402 : 1, 2, 3, 6, 67, 134, 201, 402

787 : 1, 787

646 : 1, 2, 17, 19, 34, 38, 323, 646

194 : 1, 2, 97, 194

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,787,646,194, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

787:787

646:2x 17x 19

194:2x 97

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 39649255176/(1x4)

LCM = 39649255176/4

LCM = 9912313794

Thus, we can understand that the LCM of 402,787,646,194 is 9912313794.
