Answer:
please mark as brainiest
Step-by-step explanation:
To find the co-prime of a number, find the HCF of the number first. Then, choose any number and take the HCF. All the numbers which do not have any common factor other than will be the co-prime of the chosen number.
Answer:
Explanation:
Coprime numbers are those numbers, who do not have any factor, other than
1
, common between them. In other words, two numbers are coprime if their GCF is
1
. As we may see below, this may happen even if two numbers are composite.
(2) Factors of
25
and
32
are
25
=
5
×
5
and
32
=

, as there is no common factor, they are coprime numbers.
(3) Factors of
15
and
22
are
15
=
3
×
5
and
22
=
2
×
11
, as there is no common factor, they are coprime numbers.
(4) Factors of
18
and
35
are
18
=

and
35
=

, as there is no common factor, they too are coprime numbers.
However, in case of (1) factors of
32
and
24
are
32
=

=

. Hence, they are not coprime numbers.
