Given numbers are 648,642,163,216,364

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

The LCM of 648,642,163,216,364 is 1028460888.

Find LCM of 648,642,163,216,364 with Prime Factorization

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

2 x 2 x 2 x 3 x 3 x 3 x 1 x 107 x 163 x 3 x 91 = 1028460888

Therefore, the lowest common multiple of 648,642,163,216,364 is 1028460888.

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 642 x 163 x 216 x 364 = 5331541243392

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

642 : 1, 2, 3, 6, 107, 214, 321, 642

163 : 1, 163

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

364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,642,163,216,364, is 1.

Now, the common factors can be found like this.

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

642:2x 3x 107

163:163

216:2x 2x 2x 3x 3x 3

364:2x 2x 7x 13

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 2x 2x 2x 2x 3x 3x 3x 3 = 5184

Therefore, the value for common factors is 5184.

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 = 5331541243392/(1x5184)

LCM = 5331541243392/5184

LCM = 1028460888

Thus, we can understand that the LCM of 648,642,163,216,364 is 1028460888.
