Given numbers are 178, 216, 643, 535

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

Apply this formula for all numbers.

Step1:

LCM(178, 216) = 19224

GCD(178, 216) = ( 178 x 216 ) / 19224

= 178 / 216

= 178

Step2:

LCM(2, 643) = 1286

GCD(2, 643) = ( 2 x 643 ) / 1286

= 2 / 643

= 2

Step3:

LCM(1, 535) = 535

GCD(1, 535) = ( 1 x 535 ) / 535

= 1 / 535

= 1

So, Greatest Common Divisor of 178, 216, 643, 535 is 1
