Given numbers are 669,455,669,618

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

The LCM of 669,455,669,618 is 62705370.

Find LCM of 669,455,669,618 with Prime Factorization

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

3 x 223 x 1 x 455 x 1 x 206 = 62705370

Therefore, the lowest common multiple of 669,455,669,618 is 62705370.

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 455 x 669 x 618 = 125849677590

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

455 : 1, 5, 7, 13, 35, 65, 91, 455

669 : 1, 3, 223, 669

618 : 1, 2, 3, 6, 103, 206, 309, 618

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,455,669,618, is 1.

Now, the common factors can be found like this.

669:3x 223

455:5x 7x 13

669:3x 223

618:2x 3x 103

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 223 = 2007

Therefore, the value for common factors is 2007.

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 = 125849677590/(1x2007)

LCM = 125849677590/2007

LCM = 62705370

Thus, we can understand that the LCM of 669,455,669,618 is 62705370.
