Given numbers are 961,291,291,561

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

The LCM of 961,291,291,561 is 52294737.

Find LCM of 961,291,291,561 with Prime Factorization

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

3 x 97 x 961 x 1 x 1 x 187 = 52294737

Therefore, the lowest common multiple of 961,291,291,561 is 52294737.

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.

961 x 291 x 291 x 561 = 45653305401

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.

961 : 1, 31, 961

291 : 1, 3, 97, 291

291 : 1, 3, 97, 291

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 961,291,291,561, is 1.

Now, the common factors can be found like this.

961:31x 31

291:3x 97

291:3x 97

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.

3x 3x 97 = 873

Therefore, the value for common factors is 873.

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 = 45653305401/(1x873)

LCM = 45653305401/873

LCM = 52294737

Thus, we can understand that the LCM of 961,291,291,561 is 52294737.
