Given numbers are 743,781,743,681

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

The LCM of 743,781,743,681 is 395172723.

Find LCM of 743,781,743,681 with Prime Factorization

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

743 x 1 x 781 x 1 x 681 = 395172723

Therefore, the lowest common multiple of 743,781,743,681 is 395172723.

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.

743 x 781 x 743 x 681 = 293613333189

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.

743 : 1, 743

781 : 1, 11, 71, 781

743 : 1, 743

681 : 1, 3, 227, 681

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 743,781,743,681, is 1.

Now, the common factors can be found like this.

743:743

781:11x 71

743:743

681:3x 227

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

743 = 743

Therefore, the value for common factors is 743.

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 = 293613333189/(1x743)

LCM = 293613333189/743

LCM = 395172723

Thus, we can understand that the LCM of 743,781,743,681 is 395172723.
