Given numbers are 155, 457, 208, 884

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

Apply this formula for all numbers.

Step1:

LCM(155, 457) = 70835

GCD(155, 457) = ( 155 x 457 ) / 70835

= 155 / 457

= 155

Step2:

LCM(1, 208) = 208

GCD(1, 208) = ( 1 x 208 ) / 208

= 1 / 208

= 1

Step3:

LCM(1, 884) = 884

GCD(1, 884) = ( 1 x 884 ) / 884

= 1 / 884

= 1

So, Greatest Common Divisor of 155, 457, 208, 884 is 1
