Given numbers are 679,194,670,861,644

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

The LCM of 679,194,670,861,644 is 2573993940.

Find LCM of 679,194,670,861,644 with Prime Factorization

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

2 x 7 x 97 x 1 x 1 x 335 x 123 x 46 = 2573993940

Therefore, the lowest common multiple of 679,194,670,861,644 is 2573993940.

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.

679 x 194 x 670 x 861 x 644 = 48936772787280

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.

679 : 1, 7, 97, 679

194 : 1, 2, 97, 194

670 : 1, 2, 5, 10, 67, 134, 335, 670

861 : 1, 3, 7, 21, 41, 123, 287, 861

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 679,194,670,861,644, is 1.

Now, the common factors can be found like this.

679:7x 97

194:2x 97

670:2x 5x 67

861:3x 7x 41

644:2x 2x 7x 23

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 7x 7x 97 = 19012

Therefore, the value for common factors is 19012.

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 = 48936772787280/(1x19012)

LCM = 48936772787280/19012

LCM = 2573993940

Thus, we can understand that the LCM of 679,194,670,861,644 is 2573993940.
