Given numbers are 645, 472, 832, 655

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

Apply this formula for all numbers.

Step1:

LCM(645, 472) = 304440

GCD(645, 472) = ( 645 x 472 ) / 304440

= 645 / 472

= 645

Step2:

LCM(1, 832) = 832

GCD(1, 832) = ( 1 x 832 ) / 832

= 1 / 832

= 1

Step3:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

So, Greatest Common Divisor of 645, 472, 832, 655 is 1
