720=2×2×2×5×3×3×2
gcd will be only 2
second multiple of 1
437=19×23
874=2×19×23
720=2×2×2×5×3×3×2
gcd will be only 2

Answer: GCD of 874 and 720 is 2
Step-by-step explanation:
The greatest common factor (GCF) that divides two or more integers is known as the greatest common divisor (GCD). The highest common factor is another name for it (HCF). The term "divisor" may be changed to "factor" and the adjective "greatest" may be changed to "highest" in the name "largest common divisor," resulting in various names like highest common factor (HCF)
Given : gcd of 874 and 720 is second multiple of a number
To find : the number
By doing prime factorization i.e. factoring a particular number using only prime numbers thus we get the following.
First number- 874
874=2×437
437=19×23
874=2×19×23
Second number-720
720=2×2×2×5×3×3×2
gcd will be 2 which is second multiple of 1.
