Calculate the LCM of 997,800,899,438

Given numbers are 997,800,899,438

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

The LCM of 997,800,899,438 is 157032285600.

Find LCM of 997,800,899,438 with Prime Factorization


2 997, 800, 899, 438
997, 400, 899, 219

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

2 x 997 x 400 x 899 x 219 = 157032285600

Therefore, the lowest common multiple of 997,800,899,438 is 157032285600.

LCM Formula to Find Lowest Common Multiple of 997,800,899,438

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.

997 x 800 x 899 x 438 = 314064571200

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.

997 : 1, 997

800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800

899 : 1, 29, 31, 899

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 997,800,899,438, is 1.

Now, the common factors can be found like this.

997:997

800:2x 2x 2x 2x 2x 5x 5

899:29x 31

438:2x 3x 73

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 = 314064571200/(1x2)

LCM = 314064571200/2

LCM = 157032285600

Thus, we can understand that the LCM of 997,800,899,438 is 157032285600.
