GCD of numbers is the greatest common divisor
So, the GCD (14, 55, 30, 69) = 1.
Given numbers are 14, 55, 30, 69
The list of prime factors of all numbers are
Prime factors of 14 are 2 x 7
Prime factors of 55 are 5 x 11
Prime factors of 30 are 2 x 3 x 5
Prime factors of 69 are 3 x 23
The above numbers do not have any common prime factor. So GCD is 1
Steps to Calculate GCD of 14, 55, 30, 69 using LCM Formula
Given numbers are 14, 55, 30, 69
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(14, 55) = 770
GCD(14, 55) = ( 14 x 55 ) / 770
= 14 / 55
= 14
Step2:
LCM(1, 30) = 30
GCD(1, 30) = ( 1 x 30 ) / 30
= 1 / 30
= 1
Step3:
LCM(1, 69) = 69
GCD(1, 69) = ( 1 x 69 ) / 69
= 1 / 69
= 1
So, Greatest Common Divisor of 14, 55, 30, 69 is 1
