f) (250,325)
pls ajutor!!

Answer 1

a) (30,84)

30 = 2 × 3 × 5
84 = 2² × 3 × 7
cmmdc (30, 84) = 2 × 3 = 6

 b) (440,154)

440 = 2³ × 5 × 11
154 = 2 × 7 × 11
cmmdc (440, 154) = 2 × 11 = 22

c) (160,280)

160 = 2^5 × 5
280 = 2³ × 5 × 7
cmmdc (160, 280) = 2³ × 5 = 40

 d) (51,170)
51 = 3 × 17
170 = 2 × 5 × 17
cmmdc (51,170) = 17

e) (180,550)

180 = 2² × 3² × 5
550 = 2 × 5² × 11
cmmdc (180, 550) = 2 × 5 = 10

f) (250,325)
250 = 2 × 5³
325 = 5² × 13
cmmdc (250, 325) = 5² = 25
