Given numbers are 775, 638, 905, 547

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

Apply this formula for all numbers.

Step1:

LCM(775, 638) = 494450

GCD(775, 638) = ( 775 x 638 ) / 494450

= 775 / 638

= 775

Step2:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

Step3:

LCM(1, 547) = 547

GCD(1, 547) = ( 1 x 547 ) / 547

= 1 / 547

= 1

So, Greatest Common Divisor of 775, 638, 905, 547 is 1
