Given numbers are 77,28,85,73,73

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

The LCM of 77,28,85,73,73 is 1911140.

Find LCM of 77,28,85,73,73 with Prime Factorization

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

7 x 73 x 11 x 4 x 85 x 1 x 1 = 1911140

Therefore, the lowest common multiple of 77,28,85,73,73 is 1911140.

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 28 x 85 x 73 x 73 = 976592540

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

28 : 1, 2, 4, 7, 14, 28

85 : 1, 5, 17, 85

73 : 1, 73

73 : 1, 73

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 77,28,85,73,73, is 1.

Now, the common factors can be found like this.

77:7x 11

28:2x 2x 7

85:5x 17

73:73

73:73

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

7x 73 = 511

Therefore, the value for common factors is 511.

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 = 976592540/(1x511)

LCM = 976592540/511

LCM = 1911140

Thus, we can understand that the LCM of 77,28,85,73,73 is 1911140.
