Given numbers are 164, 820, 623, 415

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

Apply this formula for all numbers.

Step1:

LCM(164, 820) = 820

GCD(164, 820) = ( 164 x 820 ) / 820

= 164 / 820

= 164

Step2:

LCM(164, 623) = 102172

GCD(164, 623) = ( 164 x 623 ) / 102172

= 164 / 623

= 164

Step3:

LCM(1, 415) = 415

GCD(1, 415) = ( 1 x 415 ) / 415

= 1 / 415

= 1

So, Greatest Common Divisor of 164, 820, 623, 415 is 1
