Given numbers are 32,90,91,745

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

The LCM of 32,90,91,745 is 19524960.

Find LCM of 32,90,91,745 with Prime Factorization

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

2 x 5 x 16 x 9 x 91 x 149 = 19524960

Therefore, the lowest common multiple of 32,90,91,745 is 19524960.

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.

32 x 90 x 91 x 745 = 195249600

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.

32 : 1, 2, 4, 8, 16, 32

90 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

91 : 1, 7, 13, 91

745 : 1, 5, 149, 745

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 32,90,91,745, is 1.

Now, the common factors can be found like this.

32:2x 2x 2x 2x 2

90:2x 3x 3x 5

91:7x 13

745:5x 149

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 195249600/(1x10)

LCM = 195249600/10

LCM = 19524960

Thus, we can understand that the LCM of 32,90,91,745 is 19524960.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 83, 40, 33, 282
