Given numbers are 77,62,57,69,171

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

The LCM of 77,62,57,69,171 is 18776142.

Find LCM of 77,62,57,69,171 with Prime Factorization

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

3 x 19 x 77 x 62 x 1 x 23 x 3 = 18776142

Therefore, the lowest common multiple of 77,62,57,69,171 is 18776142.

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.

77 x 62 x 57 x 69 x 171 = 3210720282

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.

77 : 1, 7, 11, 77

62 : 1, 2, 31, 62

57 : 1, 3, 19, 57

69 : 1, 3, 23, 69

171 : 1, 3, 9, 19, 57, 171

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 77,62,57,69,171, is 1.

Now, the common factors can be found like this.

77:7x 11

62:2x 31

57:3x 19

69:3x 23

171:3x 3x 19

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 19 = 171

Therefore, the value for common factors is 171.

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 = 3210720282/(1x171)

LCM = 3210720282/171

LCM = 18776142

Thus, we can understand that the LCM of 77,62,57,69,171 is 18776142.
