Given numbers are 646, 943, 238, 836

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

Apply this formula for all numbers.

Step1:

LCM(646, 943) = 609178

GCD(646, 943) = ( 646 x 943 ) / 609178

= 646 / 943

= 646

Step2:

LCM(1, 238) = 238

GCD(1, 238) = ( 1 x 238 ) / 238

= 1 / 238

= 1

Step3:

LCM(1, 836) = 836

GCD(1, 836) = ( 1 x 836 ) / 836

= 1 / 836

= 1

So, Greatest Common Divisor of 646, 943, 238, 836 is 1
