Given numbers are 648,555,653

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

The LCM of 648,555,653 is 78281640.

Find LCM of 648,555,653 with Prime Factorization

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

3 x 216 x 185 x 653 = 78281640

Therefore, the lowest common multiple of 648,555,653 is 78281640.

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.

648 x 555 x 653 = 234844920

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.

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

555 : 1, 3, 5, 15, 37, 111, 185, 555

653 : 1, 653

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,555,653, is 1.

Now, the common factors can be found like this.

648:2x 2x 2x 3x 3x 3x 3

555:3x 5x 37

653:653

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 = 234844920/(1x3)

LCM = 234844920/3

LCM = 78281640

Thus, we can understand that the LCM of 648,555,653 is 78281640.
