Given numbers are 691,644,278,626

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

The LCM of 691,644,278,626 is 19360789028.

Find LCM of 691,644,278,626 with Prime Factorization

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

2 x 691 x 322 x 139 x 313 = 19360789028

Therefore, the lowest common multiple of 691,644,278,626 is 19360789028.

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.

691 x 644 x 278 x 626 = 77443156112

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.

691 : 1, 691

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

278 : 1, 2, 139, 278

626 : 1, 2, 313, 626

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,644,278,626, is 1.

Now, the common factors can be found like this.

691:691

644:2x 2x 7x 23

278:2x 139

626:2x 313

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 = 77443156112/(1x4)

LCM = 77443156112/4

LCM = 19360789028

Thus, we can understand that the LCM of 691,644,278,626 is 19360789028.
