Given numbers are 905,542,478,143

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

The LCM of 905,542,478,143 is 16764160270.

Find LCM of 905,542,478,143 with Prime Factorization

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

2 x 905 x 271 x 239 x 143 = 16764160270

Therefore, the lowest common multiple of 905,542,478,143 is 16764160270.

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.

905 x 542 x 478 x 143 = 33528320540

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.

905 : 1, 5, 181, 905

542 : 1, 2, 271, 542

478 : 1, 2, 239, 478

143 : 1, 11, 13, 143

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,542,478,143, is 1.

Now, the common factors can be found like this.

905:5x 181

542:2x 271

478:2x 239

143:11x 13

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

2 = 2

Therefore, the value for common factors is 2.

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 = 33528320540/(1x2)

LCM = 33528320540/2

LCM = 16764160270

Thus, we can understand that the LCM of 905,542,478,143 is 16764160270.
