Given numbers are 798,168,861,572

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

The LCM of 798,168,861,572 is 18714696.

Find LCM of 798,168,861,572 with Prime Factorization

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

2 x 2 x 3 x 7 x 19 x 2 x 41 x 143 = 18714696

Therefore, the lowest common multiple of 798,168,861,572 is 18714696.

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.

798 x 168 x 861 x 572 = 66025447488

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.

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

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

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,168,861,572, is 1.

Now, the common factors can be found like this.

798:2x 3x 7x 19

168:2x 2x 2x 3x 7

861:3x 7x 41

572:2x 2x 11x 13

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

2x 2x 2x 3x 3x 7x 7 = 3528

Therefore, the value for common factors is 3528.

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 = 66025447488/(1x3528)

LCM = 66025447488/3528

LCM = 18714696

Thus, we can understand that the LCM of 798,168,861,572 is 18714696.
