Given numbers are 33, 42, 69, 64
The list of prime factors of all numbers are
Prime factors of 33 are 3 x 11
Prime factors of 42 are 2 x 3 x 7
Prime factors of 69 are 3 x 23
Prime factors of 64 are 2 x 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 33, 42, 69, 64 using LCM Formula
Given numbers are 33, 42, 69, 64
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(33, 42) = 462
GCD(33, 42) = ( 33 x 42 ) / 462
= 33 / 42
= 33
Step2:
LCM(3, 69) = 69
GCD(3, 69) = ( 3 x 69 ) / 69
= 3 / 69
= 3
Step3:
LCM(3, 64) = 192
GCD(3, 64) = ( 3 x 64 ) / 192
= 3 / 64
= 3
So, Greatest Common Divisor of 33, 42, 69, 64 is 1
