Calculate the LCM of 788,308,679,517

Given numbers are 788,308,679,517

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

The LCM of 788,308,679,517 is 276621884.

Find LCM of 788,308,679,517 with Prime Factorization


2 788, 308, 679, 517
2 394, 154, 679, 517
7 197, 77, 679, 517
11 197, 11, 97, 517
197, 1, 97, 47

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

2 x 2 x 7 x 11 x 197 x 1 x 97 x 47 = 276621884

Therefore, the lowest common multiple of 788,308,679,517 is 276621884.

LCM Formula to Find Lowest Common Multiple of 788,308,679,517

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.

788 x 308 x 679 x 517 = 85199540272

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.

788 : 1, 2, 4, 197, 394, 788

308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308

679 : 1, 7, 97, 679

517 : 1, 11, 47, 517

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,308,679,517, is 1.

Now, the common factors can be found like this.

788:2x 2x 197

308:2x 2x 7x 11

679:7x 97

517:11x 47

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 7x 11 = 308

Therefore, the value for common factors is 308.

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 = 85199540272/(1x308)

LCM = 85199540272/308

LCM = 276621884

Thus, we can understand that the LCM of 788,308,679,517 is 276621884.
