Question

find all the pairs of 3 digit numbers whose lcm is 3000

Answer 1

Answer:

(25)∗(31)∗(52)

Step-by-step explanation:

Power of 2: Combinations allowed (max: 5) = 6 = {0, 1, 2, 3, 4, 5}

Power of 3: Combinations allowed (max: 1) = 2 = {0, 1}

Power of 5: Combinations allowed (max: 2) = 3 = {0, 1, 2}

Total combinations possible = 6*2*3 = 36
