Given numbers are 641,691,102,608

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

The LCM of 641,691,102,608 is 13734404448.

Find LCM of 641,691,102,608 with Prime Factorization

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

2 x 641 x 691 x 51 x 304 = 13734404448

Therefore, the lowest common multiple of 641,691,102,608 is 13734404448.

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.

641 x 691 x 102 x 608 = 27468808896

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.

641 : 1, 641

691 : 1, 691

102 : 1, 2, 3, 6, 17, 34, 51, 102

608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,691,102,608, is 1.

Now, the common factors can be found like this.

641:641

691:691

102:2x 3x 17

608:2x 2x 2x 2x 2x 19

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

2 = 2

Therefore, the value for common factors is 2.

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 = 27468808896/(1x2)

LCM = 27468808896/2

LCM = 13734404448

Thus, we can understand that the LCM of 641,691,102,608 is 13734404448.
