Given numbers are 153, 437, 136, 455

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

Apply this formula for all numbers.

Step1:

LCM(153, 437) = 66861

GCD(153, 437) = ( 153 x 437 ) / 66861

= 153 / 437

= 153

Step2:

LCM(1, 136) = 136

GCD(1, 136) = ( 1 x 136 ) / 136

= 1 / 136

= 1

Step3:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

So, Greatest Common Divisor of 153, 437, 136, 455 is 1
