Given numbers are 210,985,745,673

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

The LCM of 210,985,745,673 is 4148459490.

Find LCM of 210,985,745,673 with Prime Factorization

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

5 x 42 x 197 x 149 x 673 = 4148459490

Therefore, the lowest common multiple of 210,985,745,673 is 4148459490.

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 985 x 745 x 673 = 103711487250

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

985 : 1, 5, 197, 985

745 : 1, 5, 149, 745

673 : 1, 673

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 210,985,745,673, is 1.

Now, the common factors can be found like this.

210:2x 3x 5x 7

985:5x 197

745:5x 149

673:673

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 103711487250/(1x25)

LCM = 103711487250/25

LCM = 4148459490

Thus, we can understand that the LCM of 210,985,745,673 is 4148459490.
