Given numbers are 275, 646, 669

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

Apply this formula for all numbers.

Step1:

LCM(275, 646) = 177650

GCD(275, 646) = ( 275 x 646 ) / 177650

= 275 / 646

= 275

Step2:

LCM(1, 669) = 669

GCD(1, 669) = ( 1 x 669 ) / 669

= 1 / 669

= 1

So, Greatest Common Divisor of 275, 646, 669 is 1
