LCM of:

Calculate the LCM of 778,562,380

Given numbers are 778,562,380

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

The LCM of 778,562,380 is 41537420.

Find LCM of 778,562,380 with Prime Factorization


2 778, 562, 380
389, 281, 190

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

2 x 389 x 281 x 190 = 41537420

Therefore, the lowest common multiple of 778,562,380 is 41537420.

LCM Formula to Find Lowest Common Multiple of 778,562,380

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 562 x 380 = 166149680

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

562 : 1, 2, 281, 562

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,562,380, is 2.

Now, the common factors can be found like this.

778:2x 389

562:2x 281

380:2x 2x 5x 19

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 = 166149680/(2x2)

LCM = 166149680/4

LCM = 41537420

Thus, we can understand that the LCM of 778,562,380 is 41537420.
