Calculate the LCM of 916,804,670,561

Given numbers are 916,804,670,561

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

The LCM of 916,804,670,561 is 172148460.

Find LCM of 916,804,670,561 with Prime Factorization


2 916, 804, 670, 561
2 458, 402, 335, 561
3 229, 201, 335, 561
67 229, 67, 335, 187
229, 1, 5, 187

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

2 x 2 x 3 x 67 x 229 x 1 x 5 x 187 = 172148460

Therefore, the lowest common multiple of 916,804,670,561 is 172148460.

LCM Formula to Find Lowest Common Multiple of 916,804,670,561

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.

916 x 804 x 670 x 561 = 276814723680

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.

916 : 1, 2, 4, 229, 458, 916

804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804

670 : 1, 2, 5, 10, 67, 134, 335, 670

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 916,804,670,561, is 1.

Now, the common factors can be found like this.

916:2x 2x 229

804:2x 2x 3x 67

670:2x 5x 67

561:3x 11x 17

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 3x 67 = 1608

Therefore, the value for common factors is 1608.

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 = 276814723680/(1x1608)

LCM = 276814723680/1608

LCM = 172148460

Thus, we can understand that the LCM of 916,804,670,561 is 172148460.
