Given numbers are 788, 840, 976, 821

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

Apply this formula for all numbers.

Step1:

LCM(788, 840) = 165480

GCD(788, 840) = ( 788 x 840 ) / 165480

= 788 / 840

= 788

Step2:

LCM(4, 976) = 976

GCD(4, 976) = ( 4 x 976 ) / 976

= 4 / 976

= 4

Step3:

LCM(4, 821) = 3284

GCD(4, 821) = ( 4 x 821 ) / 3284

= 4 / 821

= 4

So, Greatest Common Divisor of 788, 840, 976, 821 is 1
