Calculate the LCM of 243,975,320,622

Given numbers are 243,975,320,622

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

The LCM of 243,975,320,622 is 1571918400.

Find LCM of 243,975,320,622 with Prime Factorization


2 243, 975, 320, 622
3 243, 975, 160, 311
5 81, 325, 160, 311
81, 65, 32, 311

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

2 x 3 x 5 x 81 x 65 x 32 x 311 = 1571918400

Therefore, the lowest common multiple of 243,975,320,622 is 1571918400.

LCM Formula to Find Lowest Common Multiple of 243,975,320,622

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.

243 x 975 x 320 x 622 = 47157552000

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.

243 : 1, 3, 9, 27, 81, 243

975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975

320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320

622 : 1, 2, 311, 622

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 243,975,320,622, is 1.

Now, the common factors can be found like this.

243:3x 3x 3x 3x 3

975:3x 5x 5x 13

320:2x 2x 2x 2x 2x 2x 5

622:2x 311

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

2x 3x 5 = 30

Therefore, the value for common factors is 30.

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 = 47157552000/(1x30)

LCM = 47157552000/30

LCM = 1571918400

Thus, we can understand that the LCM of 243,975,320,622 is 1571918400.
