251,76,630 and 1255 for divisibility by 2,3,5 and 10
Answers
Answer:
To check if a number is divisible by 2we have to check the last value of the number if the value comes in the table of 2 or is divisible by 2 then the number is also divisible by 2.
To check if a number is divisible by 3 we have to add all the values of the number and if the sum is divisible by 3 then the number is also divisible by 3.
To check if a number is divisible by 5 then the last value of the number should be 0 or 5.
To check if a number is divisible by 10 then the last value of the number should be always zero.
Step-by-step explanation:
25176630 is divisible by 2 as the last as the last value of the number is 0 and 0 comes in the table of 2 so the number is also divisible by 2.
25176630 is is divisible by 3 as 2+5+1+7+6+6+3+0=30 and 30 is divisible by 3 so the number is also divisible by 3.
25176630 is divisible by 5 as the last value of the number is 0.
25176630 is divisible by 10 is the last value of the number is 0.
1255 is not divisible by 2 as the last value of the number is not even so the number is not divisible by 2.
1255 is not divisible by 3 as 1+2+5+5=13and 13 is not divisible by 3 so the number is also not divisible by 3.
1255 is divisible by 5 as the last value of the number is 5.
1255 is not divisible by 10 as the last value of the digit is not 0.
