Given numbers are 648,163,756,189

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

The LCM of 648,163,756,189 is 739368.

Find LCM of 648,163,756,189 with Prime Factorization

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

2 x 2 x 3 x 3 x 3 x 7 x 6 x 163 x 1 x 1 = 739368

Therefore, the lowest common multiple of 648,163,756,189 is 739368.

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 163 x 756 x 189 = 15091979616

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

163 : 1, 163

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

189 : 1, 3, 7, 9, 21, 27, 63, 189

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,163,756,189, is 1.

Now, the common factors can be found like this.

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

163:163

756:2x 2x 3x 3x 3x 7

189:3x 3x 3x 7

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 3x 3x 3x 3x 3x 3x 7 = 20412

Therefore, the value for common factors is 20412.

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 = 15091979616/(1x20412)

LCM = 15091979616/20412

LCM = 739368

Thus, we can understand that the LCM of 648,163,756,189 is 739368.
