Given numbers are 153, 981, 508, 438

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

Apply this formula for all numbers.

Step1:

LCM(153, 981) = 16677

GCD(153, 981) = ( 153 x 981 ) / 16677

= 153 / 981

= 153

Step2:

LCM(9, 508) = 4572

GCD(9, 508) = ( 9 x 508 ) / 4572

= 9 / 508

= 9

Step3:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 153, 981, 508, 438 is 1
