Given numbers are 256, 740, 993, 646

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

Apply this formula for all numbers.

Step1:

LCM(256, 740) = 47360

GCD(256, 740) = ( 256 x 740 ) / 47360

= 256 / 740

= 256

Step2:

LCM(4, 993) = 3972

GCD(4, 993) = ( 4 x 993 ) / 3972

= 4 / 993

= 4

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 256, 740, 993, 646 is 1
