Answer 1

a) 84 , 32
84 = 2²×3×7
32 = 2⁵
______________
cmmdc al numerelor ( 84, 32 ) = 2² = 4 

b) 150, 300 

150 = 2×3×5²
300 =2²×3×5²
___________________

cmmd  al numerelor ( 150, 300) = 2×3×5² = 150
 

 c) 14, 36, 56

14 = 2×7
36 = 2²×3²
56 = 2³×7
_______________
cmmdc al numerelor ( 14, 36, 56) = 2

 
 d) 144, 69 

144 = 2⁴x 3²
69 = 3 x 23 
____________
