Explicație pas cu pas:
a.(180,320,432)=2²=4
180=2²×3²×5¹
320= 2⁶×5¹
432=2⁴×3³
[180,320,432]=2⁶×3³×5¹=64×27×5=8640
b.(135,270,540)=5¹×3³=5×27=135
135=5¹×3³
270=3³×2¹×5¹
540=2²×3³×5¹
[135,270,540]=5¹×2²×3³=5×4×27=540
c.(270,405,162)=3³=27
270=2¹×3³×5¹
405=5¹×3⁴
162=2¹×3⁴
[270,405,162]=2¹×3⁴×5¹=2×81×5=162×5=810
d.(44,33,66)=11¹=11
44=2²×11¹
33=3¹×11¹
66=2¹×3¹×11¹
[44,33,66]=2²×11¹×3¹=4×11×3=44×3=132
