Given numbers are 669,809,210,669,423

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

The LCM of 669,809,210,669,423 is 5341851270.

Find LCM of 669,809,210,669,423 with Prime Factorization

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

3 x 223 x 1 x 809 x 70 x 1 x 141 = 5341851270

Therefore, the lowest common multiple of 669,809,210,669,423 is 5341851270.

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.

669 x 809 x 210 x 669 x 423 = 32163286496670

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.

669 : 1, 3, 223, 669

809 : 1, 809

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

669 : 1, 3, 223, 669

423 : 1, 3, 9, 47, 141, 423

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,809,210,669,423, is 1.

Now, the common factors can be found like this.

669:3x 223

809:809

210:2x 3x 5x 7

669:3x 223

423:3x 3x 47

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

3x 3x 3x 223 = 6021

Therefore, the value for common factors is 6021.

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 = 32163286496670/(1x6021)

LCM = 32163286496670/6021

LCM = 5341851270

Thus, we can understand that the LCM of 669,809,210,669,423 is 5341851270.
