Given numbers are 164, 638, 57, 891

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

Apply this formula for all numbers.

Step1:

LCM(164, 638) = 52316

GCD(164, 638) = ( 164 x 638 ) / 52316

= 164 / 638

= 164

Step2:

LCM(2, 57) = 114

GCD(2, 57) = ( 2 x 57 ) / 114

= 2 / 57

= 2

Step3:

LCM(1, 891) = 891

GCD(1, 891) = ( 1 x 891 ) / 891

= 1 / 891

= 1

So, Greatest Common Divisor of 164, 638, 57, 891 is 1
