Given numbers are 60,21,93,777

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

The LCM of 60,21,93,777 is 481740.

Find LCM of 60,21,93,777 with Prime Factorization

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

3 x 7 x 20 x 1 x 31 x 37 = 481740

Therefore, the lowest common multiple of 60,21,93,777 is 481740.

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.

60 x 21 x 93 x 777 = 91048860

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.

60 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

21 : 1, 3, 7, 21

93 : 1, 3, 31, 93

777 : 1, 3, 7, 21, 37, 111, 259, 777

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 60,21,93,777, is 3.

Now, the common factors can be found like this.

60:2x 2x 3x 5

21:3x 7

93:3x 31

777:3x 7x 37

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 7 = 63

Therefore, the value for common factors is 63.

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 = 91048860/(3x63)

LCM = 91048860/189

LCM = 481740

Thus, we can understand that the LCM of 60,21,93,777 is 481740.
