Given numbers are 168,487,657,219

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

The LCM of 168,487,657,219 is 17917704.

Find LCM of 168,487,657,219 with Prime Factorization

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

3 x 73 x 56 x 487 x 3 x 1 = 17917704

Therefore, the lowest common multiple of 168,487,657,219 is 17917704.

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.

168 x 487 x 657 x 219 = 11771931528

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.

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

487 : 1, 487

657 : 1, 3, 9, 73, 219, 657

219 : 1, 3, 73, 219

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,487,657,219, is 1.

Now, the common factors can be found like this.

168:2x 2x 2x 3x 7

487:487

657:3x 3x 73

219:3x 73

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 73 = 657

Therefore, the value for common factors is 657.

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 = 11771931528/(1x657)

LCM = 11771931528/657

LCM = 17917704

Thus, we can understand that the LCM of 168,487,657,219 is 17917704.
