Given numbers are 903,862,872,430

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

The LCM of 903,862,872,430 is 1696881480.

Find LCM of 903,862,872,430 with Prime Factorization

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

2 x 43 x 21 x 431 x 436 x 5 = 1696881480

Therefore, the lowest common multiple of 903,862,872,430 is 1696881480.

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.

903 x 862 x 872 x 430 = 291863614560

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.

903 : 1, 3, 7, 21, 43, 129, 301, 903

862 : 1, 2, 431, 862

872 : 1, 2, 4, 8, 109, 218, 436, 872

430 : 1, 2, 5, 10, 43, 86, 215, 430

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 903,862,872,430, is 1.

Now, the common factors can be found like this.

903:3x 7x 43

862:2x 431

872:2x 2x 2x 109

430:2x 5x 43

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

2x 2x 43 = 172

Therefore, the value for common factors is 172.

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 = 291863614560/(1x172)

LCM = 291863614560/172

LCM = 1696881480

Thus, we can understand that the LCM of 903,862,872,430 is 1696881480.
