165
3x5x11
3X5X11 would give you 165.
Prime factor both numbers then multiply all the numbers the number of times it appears the most. 165=3x5x11 195=3x5x13 3x5x11x13=Lcm=2145
To find the LCM of 33 and 165, you first need to break them down into their prime factors: 33 = 3x11 165 = 3x5x11 The next step is to identify any common factors. In this case both numbers have a 3 and an 11 as common factors, so we can discard one of each. Take all the other prime factors (3, 5 and 11) and multiply them to find the LCM: 3x5x11 = 165 Thus the LCM of 33 and 165 is 165.
Factors of 45 are 1, 3, 5, 9, 15 and 45.Factors of 165 are 1, 3, 5, 11, 15, 33, 55 and 165.It is clear that 15 is the greatest common factor.Alternate method:Expressing each number as the product of prime numbers can simplify the problem easily.Prime factorization of 45 = 3x3x5Prime factorization of 165 = 3x5x11.From the P.F. of both numbers it is clear that 3x5 = 15 is common.So, Greatest common factor is 15.the GCF is 15
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 42 and 385 is 7
