Given numbers are 837, 221, 438

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

Apply this formula for all numbers.

Step1:

LCM(837, 221) = 184977

GCD(837, 221) = ( 837 x 221 ) / 184977

= 837 / 221

= 837

Step2:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 837, 221, 438 is 1
