Given numbers are 851,805,745,857

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

The LCM of 851,805,745,857 is 3803336005.

Find LCM of 851,805,745,857 with Prime Factorization

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

5 x 23 x 37 x 7 x 149 x 857 = 3803336005

Therefore, the lowest common multiple of 851,805,745,857 is 3803336005.

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.

851 x 805 x 745 x 857 = 437383640575

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.

851 : 1, 23, 37, 851

805 : 1, 5, 7, 23, 35, 115, 161, 805

745 : 1, 5, 149, 745

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,805,745,857, is 1.

Now, the common factors can be found like this.

851:23x 37

805:5x 7x 23

745:5x 149

857:857

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

5x 23 = 115

Therefore, the value for common factors is 115.

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 = 437383640575/(1x115)

LCM = 437383640575/115

LCM = 3803336005

Thus, we can understand that the LCM of 851,805,745,857 is 3803336005.
