Given numbers are 678,388,710,169

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

The LCM of 678,388,710,169 is 7891262340.

Find LCM of 678,388,710,169 with Prime Factorization

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

2 x 339 x 194 x 355 x 169 = 7891262340

Therefore, the lowest common multiple of 678,388,710,169 is 7891262340.

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.

678 x 388 x 710 x 169 = 31565049360

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.

678 : 1, 2, 3, 6, 113, 226, 339, 678

388 : 1, 2, 4, 97, 194, 388

710 : 1, 2, 5, 10, 71, 142, 355, 710

169 : 1, 13, 169

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,388,710,169, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

388:2x 2x 97

710:2x 5x 71

169:13x 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 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 = 31565049360/(1x4)

LCM = 31565049360/4

LCM = 7891262340

Thus, we can understand that the LCM of 678,388,710,169 is 7891262340.
