Given numbers are 431,431,987,554

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

The LCM of 431,431,987,554 is 235669938.

Find LCM of 431,431,987,554 with Prime Factorization

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

431 x 1 x 1 x 987 x 554 = 235669938

Therefore, the lowest common multiple of 431,431,987,554 is 235669938.

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 431 x 987 x 554 = 101573743278

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

431 : 1, 431

987 : 1, 3, 7, 21, 47, 141, 329, 987

554 : 1, 2, 277, 554

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,431,987,554, is 1.

Now, the common factors can be found like this.

431:431

431:431

987:3x 7x 47

554:2x 277

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 = 101573743278/(1x431)

LCM = 101573743278/431

LCM = 235669938

Thus, we can understand that the LCM of 431,431,987,554 is 235669938.
