Question

Find the least number which when divided by 7,8 and 12leaves the same ramainder 5 in each case​

Answer 1

Answer:

173

Step-by-step explanation:

Here we need to find lcm of 7,8,12

4 | 7,8,12

2 | 7,2,3

3 | 7,1,3

7 | 7,1,1

| 1,1,1

lcm=4×2×3×7=168

but if we divide 168 by 7,8,12 we get 0 remainder

so, add 5 i.e, 168+5=173
