Given numbers are 14, 45, 55, 30
The list of prime factors of all numbers are
Prime factors of 14 are 2 x 7
Prime factors of 45 are 3 x 3 x 5
Prime factors of 55 are 5 x 11
Prime factors of 30 are 2 x 3 x 5
The above numbers do not have any common prime factor. So GCD is 1
Steps to Calculate GCD of 14, 45, 55, 30 using LCM Formula
Given numbers are 14, 45, 55, 30
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(14, 45) = 630
GCD(14, 45) = ( 14 x 45 ) / 630
= 14 / 45
= 14
Step2:
LCM(1, 55) = 55
GCD(1, 55) = ( 1 x 55 ) / 55
= 1 / 55
= 1
Step3:
LCM(1, 30) = 30
GCD(1, 30) = ( 1 x 30 ) / 30
= 1 / 30
= 1
So, Greatest Common Divisor of 14, 45, 55, 30 is 1
