Calculate the LCM of 833,918,734,420

Given numbers are 833,918,734,420

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

The LCM of 833,918,734,420 is 165083940.

Find LCM of 833,918,734,420 with Prime Factorization


2 833, 918, 734, 420
3 833, 459, 367, 210
7 833, 153, 367, 70
17 119, 153, 367, 10
7, 9, 367, 10

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

2 x 3 x 7 x 17 x 7 x 9 x 367 x 10 = 165083940

Therefore, the lowest common multiple of 833,918,734,420 is 165083940.

LCM Formula to Find Lowest Common Multiple of 833,918,734,420

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.

833 x 918 x 734 x 420 = 235739866320

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.

833 : 1, 7, 17, 49, 119, 833

918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918

734 : 1, 2, 367, 734

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 833,918,734,420, is 1.

Now, the common factors can be found like this.

833:7x 7x 17

918:2x 3x 3x 3x 17

734:2x 367

420:2x 2x 3x 5x 7

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 3x 7x 17 = 1428

Therefore, the value for common factors is 1428.

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 = 235739866320/(1x1428)

LCM = 235739866320/1428

LCM = 165083940

Thus, we can understand that the LCM of 833,918,734,420 is 165083940.
