प्रश्न
If a and b are relatively prime numbers, then what is their HCF?
उत्तर
It is given that a and b are two relatively prime numbers; we have to find their HCF.
We know that two numbers are relatively prime if they don’t have any common divisor.
Also, the factors of any prime number are 1 and the prime number itself.
For example, let a = 7 and b = 20
Thus, the factors are as follows
a = 7 × 1
And
b = 22 × 5 × 1
Now, the HCF of 7 and 20 is 1.
Thus the HCF of a and b is 1 .
