Question

2401 is divisible by which number

Answer 1

2401 is Only divisible by 1 and itself

Answer 2

Answer:

1 and 7 and itself

Step-by-step explanation:

it is divisible by 1 because every whole number is divisible by 1

it is not divisible by 2  because a number is divisible by 2 only when the last digit is 0,2,4,6, or 8

it is not divisible by 3 because a number is divisible by 3 if the sum of the digits is divisible by 3

sum of digits = 2 + 4 + 1 = 7 , not divisible by 3

it is not divisible by 4 because if a number is divisible by 4 then the last 2 number should be divisible by 4

01 = 1 not divisible by 4

it is not divisible by 5 because if a number is divissible by 5 then the last digit must be 0 or 5

it is not divisible by 6 because if a number is divisible by 6 then it is divisible by 3 & 2

there is no rule for divisibility by 7 , so let us divide and check

2401 ÷ 7 = 343

so it is divisible by 7

it is also divisible by itself because every whole numbers are divisible by themselves
