Given numbers are 645, 294, 775, 829

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

Apply this formula for all numbers.

Step1:

LCM(645, 294) = 63210

GCD(645, 294) = ( 645 x 294 ) / 63210

= 645 / 294

= 645

Step2:

LCM(3, 775) = 2325

GCD(3, 775) = ( 3 x 775 ) / 2325

= 3 / 775

= 3

Step3:

LCM(1, 829) = 829

GCD(1, 829) = ( 1 x 829 ) / 829

= 1 / 829

= 1

So, Greatest Common Divisor of 645, 294, 775, 829 is 1
