Given numbers are 646, 551, 773, 580

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

Apply this formula for all numbers.

Step1:

LCM(646, 551) = 18734

GCD(646, 551) = ( 646 x 551 ) / 18734

= 646 / 551

= 646

Step2:

LCM(19, 773) = 14687

GCD(19, 773) = ( 19 x 773 ) / 14687

= 19 / 773

= 19

Step3:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1

So, Greatest Common Divisor of 646, 551, 773, 580 is 1
