Answer:
15
Step-by-step explanation:
138, 183, 423
leaves a remainder of 3
138 - 3 = 135
183 - 3 = 180
423 - 3 = 420
we need to find out the HCF of 135, 180 and 420
135 = 3 × 3 × 3 × 5
180 = 2 × 2 × 3 × 3 × 5
420 = 2 × 2 × 3 × 5 × 7
HCF of 135, 180 and 420 is 15
therefore 15 divides 138, 183 and 423 leaving the remainder of 3
