Calculate the LCM of 198,764,575,644

Given numbers are 198,764,575,644

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

The LCM of 198,764,575,644 is 304434900.

Find LCM of 198,764,575,644 with Prime Factorization


2 198, 764, 575, 644
2 99, 382, 575, 322
23 99, 191, 575, 161
99, 191, 25, 7

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

2 x 2 x 23 x 99 x 191 x 25 x 7 = 304434900

Therefore, the lowest common multiple of 198,764,575,644 is 304434900.

LCM Formula to Find Lowest Common Multiple of 198,764,575,644

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.

198 x 764 x 575 x 644 = 56016021600

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.

198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198

764 : 1, 2, 4, 191, 382, 764

575 : 1, 5, 23, 25, 115, 575

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 198,764,575,644, is 1.

Now, the common factors can be found like this.

198:2x 3x 3x 11

764:2x 2x 191

575:5x 5x 23

644:2x 2x 7x 23

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 23 = 184

Therefore, the value for common factors is 184.

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 = 56016021600/(1x184)

LCM = 56016021600/184

LCM = 304434900

Thus, we can understand that the LCM of 198,764,575,644 is 304434900.
