Given numbers are 120, 540, 643, 235
The list of prime factors of all numbers are
Prime factors of 120 are 2 x 2 x 2 x 3 x 5
Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5
Prime factors of 643 are 643
Prime factors of 235 are 5 x 47
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 120, 540, 643, 235
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(120, 540) = 1080
GCD(120, 540) = ( 120 x 540 ) / 1080
= 120 / 540
= 120
Step2:
LCM(60, 643) = 38580
GCD(60, 643) = ( 60 x 643 ) / 38580
= 60 / 643
= 60
Step3:
LCM(1, 235) = 235
GCD(1, 235) = ( 1 x 235 ) / 235
= 1 / 235
= 1
So, Greatest Common Divisor of 120, 540, 643, 235 is 1
