Given numbers are 436, 138, 636, 811

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

Apply this formula for all numbers.

Step1:

LCM(436, 138) = 30084

GCD(436, 138) = ( 436 x 138 ) / 30084

= 436 / 138

= 436

Step2:

LCM(2, 636) = 636

GCD(2, 636) = ( 2 x 636 ) / 636

= 2 / 636

= 2

Step3:

LCM(2, 811) = 1622

GCD(2, 811) = ( 2 x 811 ) / 1622

= 2 / 811

= 2

So, Greatest Common Divisor of 436, 138, 636, 811 is 1
