Given numbers are 436, 494, 497, 689

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

Apply this formula for all numbers.

Step1:

LCM(436, 494) = 107692

GCD(436, 494) = ( 436 x 494 ) / 107692

= 436 / 494

= 436

Step2:

LCM(2, 497) = 994

GCD(2, 497) = ( 2 x 497 ) / 994

= 2 / 497

= 2

Step3:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

So, Greatest Common Divisor of 436, 494, 497, 689 is 1
