Given:
Numbers: 5², 5⁴, and 5⁶
Formula Used:
To find the HCF (Highest Common Factor) of numbers in the form of powers of a prime, we use the following formula:
HCF =
Where the base is the common prime factor, and the smallest exponent is the lowest exponent among the numbers.
Solution:
The numbers are 5², 5⁴, and 5⁶.
The common base is 5, and the smallest exponent is 2.
Therefore, the HCF is:
HCF =
Find the Highest Common Factor (HCF) of 372, 732 and 2196.
If the HCF of the expressions (x + 3) (2x² – 3x + a) and (x – 2) (3x² + 10x – b) is x² + x – 6, then what is the value of (2a – 3b) ?
The greatest number, which divides 1938 and 2337 to leave 0 and 3 respectively as remainders, is:
The greatest number, which divides 711 and 1040 to leave 48 and 20 respectively as remainders, is:
The greatest number that divides 210, 1245 and 2160 is:
There are four equilateral triangles with sides 95 cm, 76 cm, 57 cm and 152 cm. What maximum size scale (in cm) can measure all of them exactly?
The greatest number, which divides 2340 and 1551 to leave 40 and 33 respectively as remainders, is:
Deepesh has 168 litres of Oil A and 234 litres of Oil B. He fills a number of identical containers with the two types of oil in a manner that each container has only one type of oil, and all containers are completely filled. What can be the maximum volume (in litres) of each container that Deepesh uses, so that all the oil that Deepesh has, of both the types, can be poured into these containers?
HCF and LCM of two numbers are 3 and 18 respectively. If one of them is 9, find the other number.
