Given numbers are 542, 121, 489, 195

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(542, 121) = 65582

GCD(542, 121) = ( 542 x 121 ) / 65582

= 542 / 121

= 542

Step2:

LCM(1, 489) = 489

GCD(1, 489) = ( 1 x 489 ) / 489

= 1 / 489

= 1

Step3:

LCM(1, 195) = 195

GCD(1, 195) = ( 1 x 195 ) / 195

= 1 / 195

= 1

So, Greatest Common Divisor of 542, 121, 489, 195 is 1
