Calculate the LCM of 786,839,422

Given numbers are 786,839,422

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

The LCM of 786,839,422 is 139144794.

Find LCM of 786,839,422 with Prime Factorization


2 786, 839, 422
393, 839, 211

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

2 x 393 x 839 x 211 = 139144794

Therefore, the lowest common multiple of 786,839,422 is 139144794.

LCM Formula to Find Lowest Common Multiple of 786,839,422

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.

786 x 839 x 422 = 278289588

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.

786 : 1, 2, 3, 6, 131, 262, 393, 786

839 : 1, 839

422 : 1, 2, 211, 422

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,839,422, is 1.

Now, the common factors can be found like this.

786:2x 3x 131

839:839

422:2x 211

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 = 278289588/(1x2)

LCM = 278289588/2

LCM = 139144794

Thus, we can understand that the LCM of 786,839,422 is 139144794.
