Given numbers are 904, 776, 728, 391

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

Apply this formula for all numbers.

Step1:

LCM(904, 776) = 87688

GCD(904, 776) = ( 904 x 776 ) / 87688

= 904 / 776

= 904

Step2:

LCM(8, 728) = 728

GCD(8, 728) = ( 8 x 728 ) / 728

= 8 / 728

= 8

Step3:

LCM(8, 391) = 3128

GCD(8, 391) = ( 8 x 391 ) / 3128

= 8 / 391

= 8

So, Greatest Common Divisor of 904, 776, 728, 391 is 1
