The LCM of 561,733,171,865 is 20274856965.

Find LCM of 561,733,171,865 with Prime Factorization


3 561, 733, 171, 865
187, 733, 57, 865

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

3 x 187 x 733 x 57 x 865 = 20274856965

Therefore, the lowest common multiple of 561,733,171,865 is 20274856965.

LCM Formula to Find Lowest Common Multiple of 561,733,171,865

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.

561 x 733 x 171 x 865 = 60824570895

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.

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

733 : 1, 733

171 : 1, 3, 9, 19, 57, 171

865 : 1, 5, 173, 865

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,733,171,865, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

733:733

171:3x 3x 19

865:5x 173

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

3 = 3

Therefore, the value for common factors is 3.

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 = 60824570895/(1x3)

LCM = 60824570895/3

LCM = 20274856965

Thus, we can understand that the LCM of 561,733,171,865 is 20274856965.
