Given numbers are 553,637,189,868

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

The LCM of 553,637,189,868 is 168481404.

Find LCM of 553,637,189,868 with Prime Factorization

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

7 x 79 x 91 x 27 x 124 = 168481404

Therefore, the lowest common multiple of 553,637,189,868 is 168481404.

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.

553 x 637 x 189 x 868 = 57789121572

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.

553 : 1, 7, 79, 553

637 : 1, 7, 13, 49, 91, 637

189 : 1, 3, 7, 9, 21, 27, 63, 189

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

7 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 553,637,189,868, is 7.

Now, the common factors can be found like this.

553:7x 79

637:7x 7x 13

189:3x 3x 3x 7

868:2x 2x 7x 31

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

7x 7 = 49

Therefore, the value for common factors is 49.

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 = 57789121572/(7x49)

LCM = 57789121572/343

LCM = 168481404

Thus, we can understand that the LCM of 553,637,189,868 is 168481404.
