Find the HCF of 135 and 165 prime factor method
The highest common factor (HCF) of 135 and 165 is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF, we need to factorize both numbers: 135 = 3 x 3 x 3 x 5 and 165 = 3 x 5 x 11. Then, we identify the common prime factors shared by both numbers, which are 3 and 5. The product of these common factors is 3 x 5 = 15, so the HCF of 135 and 165 is 15.
The GCF is 15.
The Highest Common Factor (HCF) of 210 and 165 is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF, you can use the Euclidean algorithm, which involves dividing the larger number by the smaller number and then using the remainder as the new divisor until the remainder becomes zero. In this case, the HCF of 210 and 165 is 15.
The highest common factor (HCF) of 25 and 135 is 5. To find the HCF, you need to identify the common factors of both numbers - 25 and 135. The factors of 25 are 1, 5, and 25, while the factors of 135 are 1, 3, 5, 9, 15, 27, 45, and 135. The highest common factor among these factors is 5.
The GCF is 5.
27/40 67.5/100 = 135/200 (multiply top and bottom by 2 to make whole numbers) = 27/40 (divide top and bottom by hcf(135, 200) = 5)
The GCF is 15.
It is: 15

The Highest Common Factor (HCF) of 165, 195, and 285 is the largest number that divides all three numbers evenly. To find the HCF, we first factorize each number: 165 = 3 x 5 x 11, 195 = 3 x 5 x 13, and 285 = 3 x 5 x 19. Then, we identify the common factors among the three numbers, which are 3 and 5. Therefore, the HCF of 165, 195, and 285 is 15 (3 x 5).
Their HCF which is 1
For any two counting numbers x and y:LCM(x, y) x HCF(x, y) = Product of x and yLCM(x, y) = (Product of x and y)/HCF(x, y)Here, we have 108 and 135 & their product = 108 x 135But, HCF(108, 135) = ?So, we shall first calculate HCF by the method of prime factorization.108 = 33x22 & 135 = 33x51It is clear that 33 is the HCF of 108 and 135.So, LCM(108, 135) = (108 x 135)/33 = 4 x 135 = 540
% rate:= (135/165) x 100%= 0.8182 x 100%= 81.82%
The GCF is 15.
The GCF/HCF of 117 and 135 is 9.
The HCF is 9
They are 15 and 2145 respectively
The HCF is: 45
