Given numbers are 921,957,966,961

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

The LCM of 921,957,966,961 is 90913750158.

Find LCM of 921,957,966,961 with Prime Factorization

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

3 x 307 x 319 x 322 x 961 = 90913750158

Therefore, the lowest common multiple of 921,957,966,961 is 90913750158.

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.

921 x 957 x 966 x 961 = 818223751422

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.

921 : 1, 3, 307, 921

957 : 1, 3, 11, 29, 33, 87, 319, 957

966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966

961 : 1, 31, 961

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,957,966,961, is 1.

Now, the common factors can be found like this.

921:3x 307

957:3x 11x 29

966:2x 3x 7x 23

961:31x 31

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

3x 3 = 9

Therefore, the value for common factors is 9.

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 = 818223751422/(1x9)

LCM = 818223751422/9

LCM = 90913750158

Thus, we can understand that the LCM of 921,957,966,961 is 90913750158.
