Given numbers are 778,838,644,187

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

The LCM of 778,838,644,187 is 19628680148.

Find LCM of 778,838,644,187 with Prime Factorization

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

2 x 389 x 419 x 322 x 187 = 19628680148

Therefore, the lowest common multiple of 778,838,644,187 is 19628680148.

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.

778 x 838 x 644 x 187 = 78514720592

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.

778 : 1, 2, 389, 778

838 : 1, 2, 419, 838

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

187 : 1, 11, 17, 187

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,838,644,187, is 1.

Now, the common factors can be found like this.

778:2x 389

838:2x 419

644:2x 2x 7x 23

187:11x 17

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 78514720592/(1x4)

LCM = 78514720592/4

LCM = 19628680148

Thus, we can understand that the LCM of 778,838,644,187 is 19628680148.
