Given numbers are 717,857,430,242,861

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

The LCM of 717,857,430,242,861 is 9175625934090.

Find LCM of 717,857,430,242,861 with Prime Factorization

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

2 x 3 x 239 x 857 x 215 x 121 x 287 = 9175625934090

Therefore, the lowest common multiple of 717,857,430,242,861 is 9175625934090.

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.

717 x 857 x 430 x 242 x 861 = 55053755604540

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.

717 : 1, 3, 239, 717

857 : 1, 857

430 : 1, 2, 5, 10, 43, 86, 215, 430

242 : 1, 2, 11, 22, 121, 242

861 : 1, 3, 7, 21, 41, 123, 287, 861

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,857,430,242,861, is 1.

Now, the common factors can be found like this.

717:3x 239

857:857

430:2x 5x 43

242:2x 11x 11

861:3x 7x 41

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 55053755604540/(1x6)

LCM = 55053755604540/6

LCM = 9175625934090

Thus, we can understand that the LCM of 717,857,430,242,861 is 9175625934090.
