Given numbers are 203,133,637,420

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

The LCM of 203,133,637,420 is 21059220.

Find LCM of 203,133,637,420 with Prime Factorization

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

7 x 29 x 19 x 91 x 60 = 21059220

Therefore, the lowest common multiple of 203,133,637,420 is 21059220.

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.

203 x 133 x 637 x 420 = 7223312460

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.

203 : 1, 7, 29, 203

133 : 1, 7, 19, 133

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

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

7 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 203,133,637,420, is 7.

Now, the common factors can be found like this.

203:7x 29

133:7x 19

637:7x 7x 13

420:2x 2x 3x 5x 7

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 = 7223312460/(7x49)

LCM = 7223312460/343

LCM = 21059220

Thus, we can understand that the LCM of 203,133,637,420 is 21059220.
