Step-by-step explanation:
Divisibility rule for 2 is all no. ending with 0,2,4,6,8 = 76 and 630 are divisible with 2 whereas, 251 and 1251 are not.
Divisibility rule for 3 is that the sum of all the no. in a specific no. should be divisible by 3 = 2+5+1 = 8 , 7+6 = 13 , 6+3+0 = 9 , 1+2+5+1 = 9 , so 630 and 1251 are divisible with 3 whereas, 251 and 76 are not.
Divisibility rule for 5 is any no. ending with 0 or 5 = 630 is divisible with 5 whereas, 251, 76 and 1251 are not.
Divisibility rule for 10 is any no. ending with 0 = 630 is divisible with 5 whereas, 251, 76 and 1251 are not.
