Calculate the LCM of 488,731,712,918

Given numbers are 488,731,712,918

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

The LCM of 488,731,712,918 is 857217384.

Find LCM of 488,731,712,918 with Prime Factorization


2 488, 731, 712, 918
2 244, 731, 356, 459
2 122, 731, 178, 459
17 61, 731, 89, 459
61, 43, 89, 27

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

2 x 2 x 2 x 17 x 61 x 43 x 89 x 27 = 857217384

Therefore, the lowest common multiple of 488,731,712,918 is 857217384.

LCM Formula to Find Lowest Common Multiple of 488,731,712,918

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 731 x 712 x 918 = 233163128448

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

731 : 1, 17, 43, 731

712 : 1, 2, 4, 8, 89, 178, 356, 712

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 488,731,712,918, is 1.

Now, the common factors can be found like this.

488:2x 2x 2x 61

731:17x 43

712:2x 2x 2x 89

918:2x 3x 3x 3x 17

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 2x 2x 17 = 272

Therefore, the value for common factors is 272.

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 = 233163128448/(1x272)

LCM = 233163128448/272

LCM = 857217384

Thus, we can understand that the LCM of 488,731,712,918 is 857217384.
