Given numbers are 168, 987, 157, 424

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

Apply this formula for all numbers.

Step1:

LCM(168, 987) = 7896

GCD(168, 987) = ( 168 x 987 ) / 7896

= 168 / 987

= 168

Step2:

LCM(21, 157) = 3297

GCD(21, 157) = ( 21 x 157 ) / 3297

= 21 / 157

= 21

Step3:

LCM(1, 424) = 424

GCD(1, 424) = ( 1 x 424 ) / 424

= 1 / 424

= 1

So, Greatest Common Divisor of 168, 987, 157, 424 is 1
