Calculate the LCM of 854,280,789,794

Given numbers are 854,280,789,794

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

The LCM of 854,280,789,794 is 5350019640.

Find LCM of 854,280,789,794 with Prime Factorization


2 854, 280, 789, 794
7 427, 140, 789, 397
61, 20, 789, 397

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

2 x 7 x 61 x 20 x 789 x 397 = 5350019640

Therefore, the lowest common multiple of 854,280,789,794 is 5350019640.

LCM Formula to Find Lowest Common Multiple of 854,280,789,794

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.

854 x 280 x 789 x 794 = 149800549920

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.

854 : 1, 2, 7, 14, 61, 122, 427, 854

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

789 : 1, 3, 263, 789

794 : 1, 2, 397, 794

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 854,280,789,794, is 1.

Now, the common factors can be found like this.

854:2x 7x 61

280:2x 2x 2x 5x 7

789:3x 263

794:2x 397

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 7 = 28

Therefore, the value for common factors is 28.

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 = 149800549920/(1x28)

LCM = 149800549920/28

LCM = 5350019640

Thus, we can understand that the LCM of 854,280,789,794 is 5350019640.
