Calculate the LCM of 769,998,388,455,991

Given numbers are 769,998,388,455,991

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

The LCM of 769,998,388,455,991 is 67134175903340.

Find LCM of 769,998,388,455,991 with Prime Factorization


2 769, 998, 388, 455, 991
769, 499, 194, 455, 991

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

2 x 769 x 499 x 194 x 455 x 991 = 67134175903340

Therefore, the lowest common multiple of 769,998,388,455,991 is 67134175903340.

LCM Formula to Find Lowest Common Multiple of 769,998,388,455,991

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.

769 x 998 x 388 x 455 x 991 = 134268351806680

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.

769 : 1, 769

998 : 1, 2, 499, 998

388 : 1, 2, 4, 97, 194, 388

455 : 1, 5, 7, 13, 35, 65, 91, 455

991 : 1, 991

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,998,388,455,991, is 1.

Now, the common factors can be found like this.

769:769

998:2x 499

388:2x 2x 97

455:5x 7x 13

991:991

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

2 = 2

Therefore, the value for common factors is 2.

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 = 134268351806680/(1x2)

LCM = 134268351806680/2

LCM = 67134175903340

Thus, we can understand that the LCM of 769,998,388,455,991 is 67134175903340.
