Which pair on numbers is relatively prime? a. 14 and 91 b. 14 and 581 c. 201 and 770 d. 12 and 105

A pair of numbers is said to be co prime or relatively prime if they have no common factor.

A.

14 = 2 × 7

91 = 13 × 7

B.  14 = 2 × 7

581 =7 ×83

3. 201 =3 ×67

770 = 7 ×11×10

4. 12 = 3 ×2×2

105 = 3×5×3×5

So we can see that Option C→ 201 and 770 are relatively prime.

Step-by-step explanation:

just took the test

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing

the answer is c. 23/3
