Given numbers are 978,652,626,643

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

The LCM of 978,652,626,643 is 393662604.

Find LCM of 978,652,626,643 with Prime Factorization

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

2 x 163 x 3 x 2 x 313 x 643 = 393662604

Therefore, the lowest common multiple of 978,652,626,643 is 393662604.

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.

978 x 652 x 626 x 643 = 256668017808

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.

978 : 1, 2, 3, 6, 163, 326, 489, 978

652 : 1, 2, 4, 163, 326, 652

626 : 1, 2, 313, 626

643 : 1, 643

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,652,626,643, is 1.

Now, the common factors can be found like this.

978:2x 3x 163

652:2x 2x 163

626:2x 313

643:643

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 163 = 652

Therefore, the value for common factors is 652.

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 = 256668017808/(1x652)

LCM = 256668017808/652

LCM = 393662604

Thus, we can understand that the LCM of 978,652,626,643 is 393662604.
