Given numbers are 318,721,781,722

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

The LCM of 318,721,781,722 is 64642868598.

Find LCM of 318,721,781,722 with Prime Factorization

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

2 x 159 x 721 x 781 x 361 = 64642868598

Therefore, the lowest common multiple of 318,721,781,722 is 64642868598.

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.

318 x 721 x 781 x 722 = 129285737196

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.

318 : 1, 2, 3, 6, 53, 106, 159, 318

721 : 1, 7, 103, 721

781 : 1, 11, 71, 781

722 : 1, 2, 19, 38, 361, 722

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 318,721,781,722, is 1.

Now, the common factors can be found like this.

318:2x 3x 53

721:7x 103

781:11x 71

722:2x 19x 19

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

2 = 2

Therefore, the value for common factors is 2.

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 = 129285737196/(1x2)

LCM = 129285737196/2

LCM = 64642868598

Thus, we can understand that the LCM of 318,721,781,722 is 64642868598.
