Given numbers are 238, 128, 661, 532

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

Apply this formula for all numbers.

Step1:

LCM(238, 128) = 15232

GCD(238, 128) = ( 238 x 128 ) / 15232

= 238 / 128

= 238

Step2:

LCM(2, 661) = 1322

GCD(2, 661) = ( 2 x 661 ) / 1322

= 2 / 661

= 2

Step3:

LCM(1, 532) = 532

GCD(1, 532) = ( 1 x 532 ) / 532

= 1 / 532

= 1

So, Greatest Common Divisor of 238, 128, 661, 532 is 1
