Given numbers are 203,890,728,71

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

The LCM of 203,890,728,71 is 667033640.

Find LCM of 203,890,728,71 with Prime Factorization

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

2 x 7 x 29 x 445 x 52 x 71 = 667033640

Therefore, the lowest common multiple of 203,890,728,71 is 667033640.

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 890 x 728 x 71 = 9338470960

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

890 : 1, 2, 5, 10, 89, 178, 445, 890

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

71 : 1, 71

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 203,890,728,71, is 1.

Now, the common factors can be found like this.

203:7x 29

890:2x 5x 89

728:2x 2x 2x 7x 13

71:71

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 9338470960/(1x14)

LCM = 9338470960/14

LCM = 667033640

Thus, we can understand that the LCM of 203,890,728,71 is 667033640.

Here are some samples of LCM of two or more Numbers calculations.
