Calculate the LCM of 669,706,561,923

Given numbers are 669,706,561,923

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

The LCM of 669,706,561,923 is 81521868714.

Find LCM of 669,706,561,923 with Prime Factorization


3 669, 706, 561, 923
223, 706, 187, 923

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

3 x 223 x 706 x 187 x 923 = 81521868714

Therefore, the lowest common multiple of 669,706,561,923 is 81521868714.

LCM Formula to Find Lowest Common Multiple of 669,706,561,923

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.

669 x 706 x 561 x 923 = 244565606142

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.

669 : 1, 3, 223, 669

706 : 1, 2, 353, 706

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

923 : 1, 13, 71, 923

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,706,561,923, is 1.

Now, the common factors can be found like this.

669:3x 223

706:2x 353

561:3x 11x 17

923:13x 71

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 = 244565606142/(1x3)

LCM = 244565606142/3

LCM = 81521868714

Thus, we can understand that the LCM of 669,706,561,923 is 81521868714.
