Given numbers are 431,970,809,431

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

The LCM of 431,970,809,431 is 338218630.

Find LCM of 431,970,809,431 with Prime Factorization

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

431 x 1 x 970 x 809 x 1 = 338218630

Therefore, the lowest common multiple of 431,970,809,431 is 338218630.

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.

431 x 970 x 809 x 431 = 145772229530

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.

431 : 1, 431

970 : 1, 2, 5, 10, 97, 194, 485, 970

809 : 1, 809

431 : 1, 431

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,970,809,431, is 1.

Now, the common factors can be found like this.

431:431

970:2x 5x 97

809:809

431:431

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

431 = 431

Therefore, the value for common factors is 431.

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 = 145772229530/(1x431)

LCM = 145772229530/431

LCM = 338218630

Thus, we can understand that the LCM of 431,970,809,431 is 338218630.
