What is the LCM of 30 and 70

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
