Given numbers are 561,121,572,665

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

The LCM of 561,121,572,665 is 213393180.

Find LCM of 561,121,572,665 with Prime Factorization

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

11 x 51 x 11 x 52 x 665 = 213393180

Therefore, the lowest common multiple of 561,121,572,665 is 213393180.

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.

561 x 121 x 572 x 665 = 25820574780

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.

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

121 : 1, 11, 121

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

665 : 1, 5, 7, 19, 35, 95, 133, 665

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,121,572,665, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

121:11x 11

572:2x 2x 11x 13

665:5x 7x 19

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 25820574780/(1x121)

LCM = 25820574780/121

LCM = 213393180

Thus, we can understand that the LCM of 561,121,572,665 is 213393180.
