HCF and LCM of two numbers are 19 and 969 respectively. If one number is 57, find the other number.

  1. A
    340
  2. B
    338
  3. C
    337
  4. D
    323

Solution & Step-by-step Explanation

We know the fundamental relationship between two numbers and their HCF and LCM:
Product of two numbers=HCF×LCM
Let the first number be A=57 and the second number be B.

Given:
HCF=19
LCM=969

Substituting the values into the formula:

57×B=19×969
B=
57
19×969


Since
19
57

=3:

B=
3
969


B=323
Therefore, the other number is 323.
