Numbers that are divisible by both 4 and 5 are multiples of the least common multiple of 4 and 5, which is 20. Therefore, numbers that are divisible by 4 and 5 are multiples of 20. In other words, any number that can be expressed as 20 multiplied by an integer (e.g., 20, 40, 60, 80, etc.) is divisible by both 4 and 5.
No. Even numbers are never prime numbers. A prime number is a number that is only divisible by 1 and itself. Even numbers are always divisible by 2, so they are never prime.And 20 is also divisible by 4 and 5. Its factors are 1, 2, 4, 5, 10, and 20.
365 is divisible by these numbers: 1, 5, 73 and 365.
There aren't any prime numbers divisible by 4. Prime numbers aren't divisible by anything except 1 and the number.
Clearly, both 810 and 910 are divisible by 5. A wee trick regarding numbers that are a multiple of 3, is that the component numbers, when added together, are divisible by three. So, 654 is divisible by 3, as 6+5+4 = 15 which is divisible by 3. In your example, 810 components add up to 9, which is divisible by 3. But the components of 910 add up to 10 which is not so divisible.
No one-digit numbers are divisible by 10. 10 is divisible by 1, 2 and 5.
Divisible by 5
There are infinitely many numbers divisible by 5 and 4. 680 is one of them.
All whole numbers are divisible by 1. Numbers are divisible by 2 if they end in 2, 4, 6, 8 or 0. Numbers are divisible by 3 if the sum of their digits is divisible by 3. Numbers are divisible by 4 if the last two digits of the number are divisible by 4. Numbers are divisible by 5 if the last digit of the number is either 5 or 0. Numbers are divisible by 6 if they are divisible by 2 and 3. Numbers are divisible by 9 if the sum of their digits is equal to 9 or a multiple of 9. Numbers are divisible by 10 if the last digit of the number is 0.

No. 26 for instance the sum of the digits is 8 but not divisible by 4. 32 the sum of the digits is 5 but divisible by 4 The rules for some other numbers are 2 all even numbers are divisible by 2 3 The sum of the digits is divisible by 3 4 The last 2 numbers are divisible by 4 5 The number ends in a 0 or 5 6 The sum of the digits is divisible by 3 and is even 7 no easy method 8 The last 3 numbers are divisible by 8 9 The sum of the digits is divisible by 9
76 is divisible by some of those numbers, but not all of them. 76 is an even number that ends in 6. It is divisible by 2. The sum of the digits of 76 (13) is not evenly divisible by 3. 76 is not divisible by 3. 4 times 19 is 76. 76 is divisible by 4. Only numbers that end in 0 and 5 are divisible by 5. 76 is not divisible by 5. 6 and 9 do not divide evenly into 76, so 76 is not divisible by 6 and 9. Only numbers that end in 0 are divisible by 10. 76 is not divisible by 10. Of the numbers listed, 76 is only divisible by 2 and 4.
1, 2, 4, 5, and 10
No, Venn diagrams are not numbers or expressions and so are not divisible by 4 and 5, or by any other number!
40,000, 80,000
60 and its multiples.
Numbers for which the sum of the digits is divisible by 9. This is also true for 3. There are other divisibility/multiple tests for other numbers (e.g., numbers that are divisible by 5 end in 5 or 0; numbers whose last two digits are divisible by 4 are divisible by 4)
