Multiples of 80: 80, 160, 240, 320, 400, 480, 560, 640, 720, 800 and so on.
Least Common Multiple (LCM) of 80 and 240: 240
Average of first 5 Multiples of 80: 240
First 2 Common Multiples of 80 and 80: 80, 160
Sum of first 5 Multiples of 80: 1200
Step-by-step explanation:
80 × 1 = 80 80 × 11 = 880
80 × 2 = 160 80 × 12 = 960
80 × 3 = 240 80 × 13 = 1040
80 × 4 = 320 80 × 14 = 1120
80 × 5 = 400 80 × 15 = 1200
80 × 6 = 480 80 × 16 = 1280
80 × 7 = 560 80 × 17 = 1360
80 × 8 = 640 80 × 18 = 1440
80 × 9 = 720 80 × 19 = 1520
80 × 10 = 800 80 × 20 = 1600
