Given numbers are 771, 621, 428, 885

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

Apply this formula for all numbers.

Step1:

LCM(771, 621) = 159597

GCD(771, 621) = ( 771 x 621 ) / 159597

= 771 / 621

= 771

Step2:

LCM(3, 428) = 1284

GCD(3, 428) = ( 3 x 428 ) / 1284

= 3 / 428

= 3

Step3:

LCM(1, 885) = 885

GCD(1, 885) = ( 1 x 885 ) / 885

= 1 / 885

= 1

So, Greatest Common Divisor of 771, 621, 428, 885 is 1
