Given numbers are 21, 3, 24, 32
The list of prime factors of all numbers are
Prime factors of 21 are 3 x 7
Prime factors of 3 are 3
Prime factors of 24 are 2 x 2 x 2 x 3
Prime factors of 32 are 2 x 2 x 2 x 2 x 2
The above numbers do not have any common prime factor. So GCD is 1
Steps to Calculate GCD of 21, 3, 24, 32 using LCM Formula
Given numbers are 21, 3, 24, 32
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(21, 3) = 21
GCD(21, 3) = ( 21 x 3 ) / 21
= 21 / 3
= 21
Step2:
LCM(3, 24) = 24
GCD(3, 24) = ( 3 x 24 ) / 24
= 3 / 24
= 3
Step3:
LCM(3, 32) = 96
GCD(3, 32) = ( 3 x 32 ) / 96
= 3 / 32
= 3
So, Greatest Common Divisor of 21, 3, 24, 32 is 1
