Given numbers are 742,688,907,731

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

The LCM of 742,688,907,731 is 3935668912.

Find LCM of 742,688,907,731 with Prime Factorization

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

2 x 43 x 371 x 8 x 907 x 17 = 3935668912

Therefore, the lowest common multiple of 742,688,907,731 is 3935668912.

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.

742 x 688 x 907 x 731 = 338467526432

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.

742 : 1, 2, 7, 14, 53, 106, 371, 742

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

907 : 1, 907

731 : 1, 17, 43, 731

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,688,907,731, is 1.

Now, the common factors can be found like this.

742:2x 7x 53

688:2x 2x 2x 2x 43

907:907

731:17x 43

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

2x 43 = 86

Therefore, the value for common factors is 86.

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 = 338467526432/(1x86)

LCM = 338467526432/86

LCM = 3935668912

Thus, we can understand that the LCM of 742,688,907,731 is 3935668912.
