Given numbers are 749, 689, 649, 485

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

Apply this formula for all numbers.

Step1:

LCM(749, 689) = 516061

GCD(749, 689) = ( 749 x 689 ) / 516061

= 749 / 689

= 749

Step2:

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

= 1 / 649

= 1

Step3:

LCM(1, 485) = 485

GCD(1, 485) = ( 1 x 485 ) / 485

= 1 / 485

= 1

So, Greatest Common Divisor of 749, 689, 649, 485 is 1
