Given numbers are 669,617,420

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

The LCM of 669,617,420 is 57788220.

Find LCM of 669,617,420 with Prime Factorization

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

3 x 223 x 617 x 140 = 57788220

Therefore, the lowest common multiple of 669,617,420 is 57788220.

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 617 x 420 = 173364660

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

617 : 1, 617

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,617,420, is 1.

Now, the common factors can be found like this.

669:3x 223

617:617

420:2x 2x 3x 5x 7

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

3 = 3

Therefore, the value for common factors is 3.

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 = 173364660/(1x3)

LCM = 173364660/3

LCM = 57788220

Thus, we can understand that the LCM of 669,617,420 is 57788220.
