The least number which leaves a remainder of 3 when divided by 2, 5, 7, 10 and 15 is
213
Remainder obtained = 3
LCM of 2, 5, 7, 10 and 15 is 210.
Therefore, to get the required number we have to add 3 to the LCM = 210 + 3 = 213
∴ The least number which leaves a remainder 3 when divided by 2,5,7,10 and 15 is 213.
