Given numbers are 139,205,834,421

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

The LCM of 139,205,834,421 is 71978370.

Find LCM of 139,205,834,421 with Prime Factorization

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

139 x 1 x 205 x 6 x 421 = 71978370

Therefore, the lowest common multiple of 139,205,834,421 is 71978370.

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.

139 x 205 x 834 x 421 = 10004993430

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.

139 : 1, 139

205 : 1, 5, 41, 205

834 : 1, 2, 3, 6, 139, 278, 417, 834

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 139,205,834,421, is 1.

Now, the common factors can be found like this.

139:139

205:5x 41

834:2x 3x 139

421:421

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

139 = 139

Therefore, the value for common factors is 139.

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 = 10004993430/(1x139)

LCM = 10004993430/139

LCM = 71978370

Thus, we can understand that the LCM of 139,205,834,421 is 71978370.
