Calculate the LCM of 778,520,988,177

Given numbers are 778,520,988,177

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

The LCM of 778,520,988,177 is 680267640.

Find LCM of 778,520,988,177 with Prime Factorization


2 778, 520, 988, 177
2 389, 260, 494, 177
13 389, 130, 247, 177
389, 10, 19, 177

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

2 x 2 x 13 x 389 x 10 x 19 x 177 = 680267640

Therefore, the lowest common multiple of 778,520,988,177 is 680267640.

LCM Formula to Find Lowest Common Multiple of 778,520,988,177

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 520 x 988 x 177 = 70747834560

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

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

177 : 1, 3, 59, 177

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,520,988,177, is 1.

Now, the common factors can be found like this.

778:2x 389

520:2x 2x 2x 5x 13

988:2x 2x 13x 19

177:3x 59

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 2x 13 = 104

Therefore, the value for common factors is 104.

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 = 70747834560/(1x104)

LCM = 70747834560/104

LCM = 680267640

Thus, we can understand that the LCM of 778,520,988,177 is 680267640.
