Calculate the LCM of 738,818,400,625

Given numbers are 738,818,400,625

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

The LCM of 738,818,400,625 is 1509210000.

Find LCM of 738,818,400,625 with Prime Factorization


2 738, 818, 400, 625
5 369, 409, 200, 625
5 369, 409, 40, 125
369, 409, 8, 25

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

2 x 5 x 5 x 369 x 409 x 8 x 25 = 1509210000

Therefore, the lowest common multiple of 738,818,400,625 is 1509210000.

LCM Formula to Find Lowest Common Multiple of 738,818,400,625

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.

738 x 818 x 400 x 625 = 150921000000

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.

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

818 : 1, 2, 409, 818

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

625 : 1, 5, 25, 125, 625

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 738,818,400,625, is 1.

Now, the common factors can be found like this.

738:2x 3x 3x 41

818:2x 409

400:2x 2x 2x 2x 5x 5

625:5x 5x 5x 5

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 5x 5 = 100

Therefore, the value for common factors is 100.

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 = 150921000000/(1x100)

LCM = 150921000000/100

LCM = 1509210000

Thus, we can understand that the LCM of 738,818,400,625 is 1509210000.
