Given numbers are 680, 344, 787, 497

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

Apply this formula for all numbers.

Step1:

LCM(680, 344) = 29240

GCD(680, 344) = ( 680 x 344 ) / 29240

= 680 / 344

= 680

Step2:

LCM(8, 787) = 6296

GCD(8, 787) = ( 8 x 787 ) / 6296

= 8 / 787

= 8

Step3:

LCM(1, 497) = 497

GCD(1, 497) = ( 1 x 497 ) / 497

= 1 / 497

= 1

So, Greatest Common Divisor of 680, 344, 787, 497 is 1
