Calculate the LCM of 780,415,994,629

Given numbers are 780,415,994,629

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

The LCM of 780,415,994,629 is 20238565620.

Find LCM of 780,415,994,629 with Prime Factorization


2 780, 415, 994, 629
5 390, 415, 497, 629
78, 83, 497, 629

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

2 x 5 x 78 x 83 x 497 x 629 = 20238565620

Therefore, the lowest common multiple of 780,415,994,629 is 20238565620.

LCM Formula to Find Lowest Common Multiple of 780,415,994,629

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.

780 x 415 x 994 x 629 = 202385656200

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.

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

415 : 1, 5, 83, 415

994 : 1, 2, 7, 14, 71, 142, 497, 994

629 : 1, 17, 37, 629

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,415,994,629, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

415:5x 83

994:2x 7x 71

629:17x 37

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 202385656200/(1x10)

LCM = 202385656200/10

LCM = 20238565620

Thus, we can understand that the LCM of 780,415,994,629 is 20238565620.
