Given numbers are 771, 186, 969, 643

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

Apply this formula for all numbers.

Step1:

LCM(771, 186) = 47802

GCD(771, 186) = ( 771 x 186 ) / 47802

= 771 / 186

= 771

Step2:

LCM(3, 969) = 969

GCD(3, 969) = ( 3 x 969 ) / 969

= 3 / 969

= 3

Step3:

LCM(3, 643) = 1929

GCD(3, 643) = ( 3 x 643 ) / 1929

= 3 / 643

= 3

So, Greatest Common Divisor of 771, 186, 969, 643 is 1
