Given numbers are 851,470,818,854

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

The LCM of 851,470,818,854 is 69851960710.

Find LCM of 851,470,818,854 with Prime Factorization

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

2 x 851 x 235 x 409 x 427 = 69851960710

Therefore, the lowest common multiple of 851,470,818,854 is 69851960710.

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 470 x 818 x 854 = 279407842840

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

470 : 1, 2, 5, 10, 47, 94, 235, 470

818 : 1, 2, 409, 818

854 : 1, 2, 7, 14, 61, 122, 427, 854

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,470,818,854, is 1.

Now, the common factors can be found like this.

851:23x 37

470:2x 5x 47

818:2x 409

854:2x 7x 61

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 279407842840/(1x4)

LCM = 279407842840/4

LCM = 69851960710

Thus, we can understand that the LCM of 851,470,818,854 is 69851960710.
