Question

find the least no. which when divided by 12,16,24 and 36 leaves a reminder 7 in each case​

Answer 1

Answer:

The smallest number which divides 12 16 24 and 36 is 144. But we have a condition that it leaves a remainder of 7. So we add 7 to the LCM (144+7=151). Hence the smallest number that when divided by 12 16 24 and 36 leaves a remainder 7 is 151.

Answer 2

Answer:

For this particular sum we need to find the LCM of the given numbers.

The smallest number which when divided by 12 16 24 and 36 = LCM of 12 16 24 and 36

12 = 2x2x3

16 = 2x2x2×2

24 = 2x2x2x3

36 = 2x2x3x3

LCM = 144

The smallest number which divides 12 16 24 and 36 is 144. But we have a condition that it leaves a remainder of 7. So we add 7 to the LCM (144+7=151).

Hence the smallest number that when divided by 12 16 24 and 36 leaves a remainder 7 is 151.
