Calculate the LCM of 688,503,696,781

Given numbers are 688,503,696,781

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

The LCM of 688,503,696,781 is 23514010608.

Find LCM of 688,503,696,781 with Prime Factorization


2 688, 503, 696, 781
2 344, 503, 348, 781
2 172, 503, 174, 781
86, 503, 87, 781

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

2 x 2 x 2 x 86 x 503 x 87 x 781 = 23514010608

Therefore, the lowest common multiple of 688,503,696,781 is 23514010608.

LCM Formula to Find Lowest Common Multiple of 688,503,696,781

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.

688 x 503 x 696 x 781 = 188112084864

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.

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

503 : 1, 503

696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,503,696,781, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

503:503

696:2x 2x 2x 3x 29

781:11x 71

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 2 = 8

Therefore, the value for common factors is 8.

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 = 188112084864/(1x8)

LCM = 188112084864/8

LCM = 23514010608

Thus, we can understand that the LCM of 688,503,696,781 is 23514010608.
