Given numbers are 542,307,389,921

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

The LCM of 542,307,389,921 is 194181798.

Find LCM of 542,307,389,921 with Prime Factorization

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

307 x 542 x 1 x 389 x 3 = 194181798

Therefore, the lowest common multiple of 542,307,389,921 is 194181798.

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.

542 x 307 x 389 x 921 = 59613811986

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.

542 : 1, 2, 271, 542

307 : 1, 307

389 : 1, 389

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 542,307,389,921, is 1.

Now, the common factors can be found like this.

542:2x 271

307:307

389:389

921:3x 307

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

307 = 307

Therefore, the value for common factors is 307.

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 = 59613811986/(1x307)

LCM = 59613811986/307

LCM = 194181798

Thus, we can understand that the LCM of 542,307,389,921 is 194181798.
