Given numbers are 210,778,137,421

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

The LCM of 210,778,137,421 is 4711634130.

Find LCM of 210,778,137,421 with Prime Factorization

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

2 x 105 x 389 x 137 x 421 = 4711634130

Therefore, the lowest common multiple of 210,778,137,421 is 4711634130.

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.

210 x 778 x 137 x 421 = 9423268260

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.

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

778 : 1, 2, 389, 778

137 : 1, 137

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 210,778,137,421, is 1.

Now, the common factors can be found like this.

210:2x 3x 5x 7

778:2x 389

137:137

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.

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 = 9423268260/(1x2)

LCM = 9423268260/2

LCM = 4711634130

Thus, we can understand that the LCM of 210,778,137,421 is 4711634130.
