The least number which when divided by 2, 7, 5 and 10 leaves zero remainder in each case and when divided by 13 leaves a remainder of 5 is: |
70 72 67 52 |
70 |
Since we are looking for the number that leaves 0 as remainder with 2, 7, 5 and 10, we are actually looking for the LCM. LCM of 2, 7, 5 and 10 =2 × 5 × 7 × 10 = 70 \(\frac{70}{13}\) = 5 remainder So, the answer is 70 |
