Given numbers are 642,746,526,946,679

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

The LCM of 642,746,526,946,679 is 20226955704186.

Find LCM of 642,746,526,946,679 with Prime Factorization

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

2 x 321 x 373 x 263 x 473 x 679 = 20226955704186

Therefore, the lowest common multiple of 642,746,526,946,679 is 20226955704186.

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.

642 x 746 x 526 x 946 x 679 = 161815645633488

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.

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

746 : 1, 2, 373, 746

526 : 1, 2, 263, 526

946 : 1, 2, 11, 22, 43, 86, 473, 946

679 : 1, 7, 97, 679

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,746,526,946,679, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

746:2x 373

526:2x 263

946:2x 11x 43

679:7x 97

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 2 = 8

Therefore, the value for common factors is 8.

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 = 161815645633488/(1x8)

LCM = 161815645633488/8

LCM = 20226955704186

Thus, we can understand that the LCM of 642,746,526,946,679 is 20226955704186.
