Given numbers are 661,698,166,657,401

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

The LCM of 661,698,166,657,401 is 10088920890918.

Find LCM of 661,698,166,657,401 with Prime Factorization

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

2 x 661 x 349 x 83 x 657 x 401 = 10088920890918

Therefore, the lowest common multiple of 661,698,166,657,401 is 10088920890918.

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.

661 x 698 x 166 x 657 x 401 = 20177841781836

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.

661 : 1, 661

698 : 1, 2, 349, 698

166 : 1, 2, 83, 166

657 : 1, 3, 9, 73, 219, 657

401 : 1, 401

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,698,166,657,401, is 1.

Now, the common factors can be found like this.

661:661

698:2x 349

166:2x 83

657:3x 3x 73

401:401

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

2 = 2

Therefore, the value for common factors is 2.

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 = 20177841781836/(1x2)

LCM = 20177841781836/2

LCM = 10088920890918

Thus, we can understand that the LCM of 661,698,166,657,401 is 10088920890918.
