Calculate the LCM of 771,698,698,160

Given numbers are 771,698,698,160

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

The LCM of 771,698,698,160 is 43052640.

Find LCM of 771,698,698,160 with Prime Factorization


2 771, 698, 698, 160
349 771, 349, 349, 80
771, 1, 1, 80

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

2 x 349 x 771 x 1 x 1 x 80 = 43052640

Therefore, the lowest common multiple of 771,698,698,160 is 43052640.

LCM Formula to Find Lowest Common Multiple of 771,698,698,160

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.

771 x 698 x 698 x 160 = 60101485440

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.

771 : 1, 3, 257, 771

698 : 1, 2, 349, 698

698 : 1, 2, 349, 698

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,698,698,160, is 1.

Now, the common factors can be found like this.

771:3x 257

698:2x 349

698:2x 349

160:2x 2x 2x 2x 2x 5

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 349 = 1396

Therefore, the value for common factors is 1396.

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 = 60101485440/(1x1396)

LCM = 60101485440/1396

LCM = 43052640

Thus, we can understand that the LCM of 771,698,698,160 is 43052640.
