Given numbers are 821, 153, 232, 138

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

Apply this formula for all numbers.

Step1:

LCM(821, 153) = 125613

GCD(821, 153) = ( 821 x 153 ) / 125613

= 821 / 153

= 821

Step2:

LCM(1, 232) = 232

GCD(1, 232) = ( 1 x 232 ) / 232

= 1 / 232

= 1

Step3:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

So, Greatest Common Divisor of 821, 153, 232, 138 is 1
