Firstly, we will find the LCM of the given numbers, i.e. , 20, 25, 35 and 40
20 => 2 × 5 × 2
25 => 5 × 5
35 => 7 × 5
40 => 2 × 5 × 2 × 2
LCM of 20, 25, 35 and 40 => 2 × 2 × 5 × 5 × 7 × 2 = 1400
When divided 20, 25, 35 and 40 by 14, 19, 29 and 34, i.e , 6 is less than the divisor.
So, we will subtract 6 from 1400
✒ 1400 - 6 = 1394
∴ The required number is
