Here is your answer:
To find,
The smallest number when divided by 30, 40 & 60. leaving the same remainder 7 in each case.
Solution:
Now let us find the LCM of these three numbers.
⇒ 30 = 2 × 3 × 5
⇒ 40 = 2³ × 5
⇒ 60 = 2² × 3 × 5.
The LCM = 2³ × 3 × 5 = 120.
Then, 120 is the number which is exactly divisible.
Then, 120 + 7 = 127. This number leaves remainder 7 when divided by those 3 number.
Hence 127 is the smallest number that leaves 7 as remainder which divided by those numbers.
