Given numbers are 401,143,869,661

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

The LCM of 401,143,869,661 is 2994394117.

Find LCM of 401,143,869,661 with Prime Factorization

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

11 x 401 x 13 x 79 x 661 = 2994394117

Therefore, the lowest common multiple of 401,143,869,661 is 2994394117.

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.

401 x 143 x 869 x 661 = 32938335287

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.

401 : 1, 401

143 : 1, 11, 13, 143

869 : 1, 11, 79, 869

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,143,869,661, is 1.

Now, the common factors can be found like this.

401:401

143:11x 13

869:11x 79

661:661

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

11 = 11

Therefore, the value for common factors is 11.

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 = 32938335287/(1x11)

LCM = 32938335287/11

LCM = 2994394117

Thus, we can understand that the LCM of 401,143,869,661 is 2994394117.
