Given numbers are 677,802,921,742

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

The LCM of 677,802,921,742 is 185522495214.

Find LCM of 677,802,921,742 with Prime Factorization

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

2 x 677 x 401 x 921 x 371 = 185522495214

Therefore, the lowest common multiple of 677,802,921,742 is 185522495214.

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.

677 x 802 x 921 x 742 = 371044990428

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.

677 : 1, 677

802 : 1, 2, 401, 802

921 : 1, 3, 307, 921

742 : 1, 2, 7, 14, 53, 106, 371, 742

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 677,802,921,742, is 1.

Now, the common factors can be found like this.

677:677

802:2x 401

921:3x 307

742:2x 7x 53

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 = 371044990428/(1x2)

LCM = 371044990428/2

LCM = 185522495214

Thus, we can understand that the LCM of 677,802,921,742 is 185522495214.
