Given numbers are 654,669,686,214

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

The LCM of 654,669,686,214 is 5352547242.

Find LCM of 654,669,686,214 with Prime Factorization

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

2 x 3 x 109 x 223 x 343 x 107 = 5352547242

Therefore, the lowest common multiple of 654,669,686,214 is 5352547242.

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.

654 x 669 x 686 x 214 = 64230566904

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.

654 : 1, 2, 3, 6, 109, 218, 327, 654

669 : 1, 3, 223, 669

686 : 1, 2, 7, 14, 49, 98, 343, 686

214 : 1, 2, 107, 214

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,669,686,214, is 1.

Now, the common factors can be found like this.

654:2x 3x 109

669:3x 223

686:2x 7x 7x 7

214:2x 107

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

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 64230566904/(1x12)

LCM = 64230566904/12

LCM = 5352547242

Thus, we can understand that the LCM of 654,669,686,214 is 5352547242.
