Calculate the LCM of 488,169,689,385

Given numbers are 488,169,689,385

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

The LCM of 488,169,689,385 is 1682841160.

Find LCM of 488,169,689,385 with Prime Factorization


13 488, 169, 689, 385
488, 13, 53, 385

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

13 x 488 x 13 x 53 x 385 = 1682841160

Therefore, the lowest common multiple of 488,169,689,385 is 1682841160.

LCM Formula to Find Lowest Common Multiple of 488,169,689,385

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.

488 x 169 x 689 x 385 = 21876935080

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.

488 : 1, 2, 4, 8, 61, 122, 244, 488

169 : 1, 13, 169

689 : 1, 13, 53, 689

385 : 1, 5, 7, 11, 35, 55, 77, 385

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 488,169,689,385, is 1.

Now, the common factors can be found like this.

488:2x 2x 2x 61

169:13x 13

689:13x 53

385:5x 7x 11

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

13 = 13

Therefore, the value for common factors is 13.

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 = 21876935080/(1x13)

LCM = 21876935080/13

LCM = 1682841160

Thus, we can understand that the LCM of 488,169,689,385 is 1682841160.
