Given numbers are 781,681,202,404

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

The LCM of 781,681,202,404 is 214871844.

Find LCM of 781,681,202,404 with Prime Factorization

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

2 x 101 x 781 x 681 x 1 x 2 = 214871844

Therefore, the lowest common multiple of 781,681,202,404 is 214871844.

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.

781 x 681 x 202 x 404 = 43404112488

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.

781 : 1, 11, 71, 781

681 : 1, 3, 227, 681

202 : 1, 2, 101, 202

404 : 1, 2, 4, 101, 202, 404

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,681,202,404, is 1.

Now, the common factors can be found like this.

781:11x 71

681:3x 227

202:2x 101

404:2x 2x 101

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

2x 101 = 202

Therefore, the value for common factors is 202.

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 = 43404112488/(1x202)

LCM = 43404112488/202

LCM = 214871844

Thus, we can understand that the LCM of 781,681,202,404 is 214871844.
