The H.C.F. of two integers is 13 and their product is 2028. The total number of such pairings is as follows:
A. 1
B. 2
C. 3
D. 4
Answer:B
The H.C.F. of two integers is 13 and their product is 2028. The total number of such pairings is as follows:
A. 1 B. 2 C. 3 D. 4
Explanation: Let's use the numbers 13a and 13b as an example.As a result, 13a x 13b = 2028.ab = twelve.(1, 12) and (1, 12) are now the co-primes for product 12. (3, 4). [Note: If two numbers a and b have no common positive factor other than 1 or, equivalently, if their largest common divisor is 1, they are said to be coprime or comparatively prime.].As a result, the needed numbers are (13 x 1, 13 x 12) and (13 x 1, 13 x 12). (13 x 3, 13 x 4).There are clearly two such pairings.
