Given numbers are 60, 30, 23, 42
The list of prime factors of all numbers are
Prime factors of 60 are 2 x 2 x 3 x 5
Prime factors of 30 are 2 x 3 x 5
Prime factors of 23 are 23
Prime factors of 42 are 2 x 3 x 7
The above numbers do not have any common prime factor. So GCD is 1
Steps to Calculate GCD of 60, 30, 23, 42 using LCM Formula
Given numbers are 60, 30, 23, 42
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(60, 30) = 60
GCD(60, 30) = ( 60 x 30 ) / 60
= 60 / 30
= 60
Step2:
LCM(30, 23) = 690
GCD(30, 23) = ( 30 x 23 ) / 690
= 30 / 23
= 30
Step3:
LCM(1, 42) = 42
GCD(1, 42) = ( 1 x 42 ) / 42
= 1 / 42
= 1
So, Greatest Common Divisor of 60, 30, 23, 42 is 1
