Calculate the LCM of 778,646,872,738

Given numbers are 778,646,872,738

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

The LCM of 778,646,872,738 is 40429183896.

Find LCM of 778,646,872,738 with Prime Factorization


2 778, 646, 872, 738
389, 323, 436, 369

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

2 x 389 x 323 x 436 x 369 = 40429183896

Therefore, the lowest common multiple of 778,646,872,738 is 40429183896.

LCM Formula to Find Lowest Common Multiple of 778,646,872,738

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.

778 x 646 x 872 x 738 = 323433471168

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.

778 : 1, 2, 389, 778

646 : 1, 2, 17, 19, 34, 38, 323, 646

872 : 1, 2, 4, 8, 109, 218, 436, 872

738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,646,872,738, is 2.

Now, the common factors can be found like this.

778:2x 389

646:2x 17x 19

872:2x 2x 2x 109

738:2x 3x 3x 41

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 323433471168/(2x4)

LCM = 323433471168/8

LCM = 40429183896

Thus, we can understand that the LCM of 778,646,872,738 is 40429183896.
