Given numbers are 259, 646, 921, 415

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

Apply this formula for all numbers.

Step1:

LCM(259, 646) = 167314

GCD(259, 646) = ( 259 x 646 ) / 167314

= 259 / 646

= 259

Step2:

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

= 1 / 921

= 1

Step3:

LCM(1, 415) = 415

GCD(1, 415) = ( 1 x 415 ) / 415

= 1 / 415

= 1

So, Greatest Common Divisor of 259, 646, 921, 415 is 1
