Given numbers are 7,687,133,931

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

The LCM of 7,687,133,931 is 639597.

Find LCM of 7,687,133,931 with Prime Factorization

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

7 x 19 x 1 x 687 x 1 x 7 = 639597

Therefore, the lowest common multiple of 7,687,133,931 is 639597.

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.

7 x 687 x 133 x 931 = 595464807

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.

7 : 1, 7

687 : 1, 3, 229, 687

133 : 1, 7, 19, 133

931 : 1, 7, 19, 49, 133, 931

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,687,133,931, is 1.

Now, the common factors can be found like this.

7:7

687:3x 229

133:7x 19

931:7x 7x 19

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

7x 7x 19 = 931

Therefore, the value for common factors is 931.

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 = 595464807/(1x931)

LCM = 595464807/931

LCM = 639597

Thus, we can understand that the LCM of 7,687,133,931 is 639597.
