210
Step-by-step explanation:
LCM means lowest common multiple
Step 1 : write out multiples of 30
30 X 1 = 30
30 X 2 = 60
30 X 3 = 90
30 X 4 = 120
30 X 5 = 150
30 X 6 = 180
30 X 7 = 210
30 X 8 = 240
Step 2: write out multiples of 70
70 X 1 = 70
70 X 2 = 140
70 X 3 = 210
70 X 4 = 280
Step 3 : the lowest multiple of 30 and 70 that are common to each other is 210
Hence, the LCM of 30 and 70 is 210
