Jill has 21 red roses and 28 white roses she wants to make arguments of flowers that look exactly the same with the same number of 5 verses in the same number of white roses and a shark in it what is the greatest number of argument she can make

To create the arguments of flowers with the same number of verses and a shark in it, we need to find the greatest common divisor (GCD) between the number of red roses (21) and white roses (28).

The prime factorization of 21 is 3 * 7.
The prime factorization of 28 is 2^2 * 7.

To find the GCD, we take the common prime factors with the lowest exponent:
GCD = 7

Therefore, the greatest number of arguments Jill can make with the same number of verses and a shark in it is 7.
