The prime numbers that are factors of 20, 30, 40, 50, and 60 are 2 and 5. These numbers are prime because they are only divisible by 1 and themselves. When you factorize each of the given numbers, you will find that 2 and 5 are common prime factors among them.
Oh, dude, you're hitting me with the math questions? Alright, so the prime numbers that are factors of those numbers are 2 and 5. Like, 2 goes into all of them, and 5 is in there too. So, yeah, those are the prime party crashers for 20, 30, 40, 50, and 60.
Well, honey, the two prime numbers that are factors of all those numbers are 2 and 5. They may not be the life of the party, but they sure know how to divide those multiples like a pro. So, next time you're stuck with numbers like these, just remember to call on good ol' 2 and 5 to save the day.

What is the prime numbers of 20-30?
Prime numbers only have factors of 1 and themselves: 23, 29
What numbers below 20 have 2 factors?
A number will always have 1 and itself as factors. And thus the only numbers with 2 factors will be prime numbers. The only prime numbers below 20 are 2, 3, 5, 7, 11, 13, 17 and 19, and thus these are the only numbers below 20 that have 2 factors.
What is the GCF of 28 20 and 40?
To find the GCF, you first need to break the numbers down into their prime factors: 28 = 2x2x7 20 = 2x2x5 40 = 2x2x2x5 The next step is to find any common prime factors. In this case, all three numbers have two 2s as prime factors. Multiply these and you get 4. Therefore the GCF of 28, 20 and 40 is 4.
What 2 prime numbers equal 20?
7 + 13 = 20 Note that there are no two prime numbers x and y that multiply to 20.

Is twenty prime or composite?
Twenty is composite. It has the factors 1, 2, 4 ,5, 10, and 20. Prime numbers have exactly two factors. Composite numbers have three or more.
Are 9 and 20 co-prime numbers?
No because they are composite numbers having more than two factors
A number more than two factors?
'''They called composite numbers.''' '''Composite numbers are when they have more than two factors.''' '''A prime number is when it only has 2 factors no more or less.''' '''EX : 20''' '''Factors Of 20 : 1, 20, 2, 10, 4, 5.'''
Why 23 and 29 are the prime numbers between 20 and 30?
Because the other numbers have more than two factors
What is the HCF of 20 and 12?
To work this out, you need to write both numbers as their prime factors: 20 = 2x2x5 12 = 2x2x3 The next step is to identify any common prime factors. In this case both numbers have two 2s as prime factors. Multiply these together and you get 4. Therefore 4 is the HCF of 20 and 12.
Why is 23 and 29 the prime numbers between 20 and 30?
They are the only ones with just two factors.
What composite numbers between 20 and30?
All of them except 23 and 29 which are prime numbers having only two factors
Can two numbers have 20 as HCF and 535 as LCM?
HCF of 20 means the two numbers have common prime factors of 2, 2 and 5. However, LCM of 535 means that both of the numbers are odd. This cannot be the case if they have a prime factor of 2. Thus two numbers cannot have 20 as hcf and 535 as lcm.
