Calculate the LCM of 897,640,561,535

Given numbers are 897,640,561,535

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

The LCM of 897,640,561,535 is 11486766720.

Find LCM of 897,640,561,535 with Prime Factorization


3 897, 640, 561, 535
5 299, 640, 187, 535
299, 128, 187, 107

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

3 x 5 x 299 x 128 x 187 x 107 = 11486766720

Therefore, the lowest common multiple of 897,640,561,535 is 11486766720.

LCM Formula to Find Lowest Common Multiple of 897,640,561,535

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.

897 x 640 x 561 x 535 = 172301500800

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.

897 : 1, 3, 13, 23, 39, 69, 299, 897

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

561 : 1, 3, 11, 17, 33, 51, 187, 561

535 : 1, 5, 107, 535

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,640,561,535, is 1.

Now, the common factors can be found like this.

897:3x 13x 23

640:2x 2x 2x 2x 2x 2x 2x 5

561:3x 11x 17

535:5x 107

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 172301500800/(1x15)

LCM = 172301500800/15

LCM = 11486766720

Thus, we can understand that the LCM of 897,640,561,535 is 11486766720.
