Given numbers are 57,77,121

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

The LCM of 57,77,121 is 48279.

Find LCM of 57,77,121 with Prime Factorization

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

11 x 57 x 7 x 11 = 48279

Therefore, the lowest common multiple of 57,77,121 is 48279.

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.

57 x 77 x 121 = 531069

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.

57 : 1, 3, 19, 57

77 : 1, 7, 11, 77

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 57,77,121, is 1.

Now, the common factors can be found like this.

57:3x 19

77:7x 11

121:11x 11

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 = 531069/(1x11)

LCM = 531069/11

LCM = 48279

Thus, we can understand that the LCM of 57,77,121 is 48279.
