a) 27, 81, 63 b) 1023, 11, 121 c) 8, 12, 256 d) 361,19, 38
e) 45, 9, 27 f) 98, 27, 81 g) 289, 34, 4 h) 4, 12, 36

Answer 1

a) 27, 81, 63MCD = 9MCM = 567       27 = 3*3*3 = 3^3     81 = 3*3*3*3 = 3^4
b)1023, 11, 121MCD = 11MCM = 11253       1023 = 3*11*31     11 = 11
c)8, 12, 256MCD = 4MCM = 768           8 = 2*2*2 = 2^3       12 = 2*2*3 = 2^2*3
d)61, 19, 38MCD = 19MCM = 7223       61 = 19*19 = 19^2     19 = 19
e)45, 9, 27MCD = 9MCM = 135        45 = 3*3*5 = 3^2*5        9 = 3*3 = 3^2
f)98, 27, 81MCD = 1MCM = 7938        98 = 2*7*7 = 2*7^2      27 = 3*3*3 = 3^3
g)289, 34, 4MCD = 1MCM = 1156      289 = 17*17 = 17^2      34 = 2*17
h)4, 12, 36MCD = 4MCM = 36    4 = 2*2 = 2^2     12 = 2*2*3 = 2^2*3
