Given numbers are 669, 957, 308, 215

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

Apply this formula for all numbers.

Step1:

LCM(669, 957) = 213411

GCD(669, 957) = ( 669 x 957 ) / 213411

= 669 / 957

= 669

Step2:

LCM(3, 308) = 924

GCD(3, 308) = ( 3 x 308 ) / 924

= 3 / 308

= 3

Step3:

LCM(1, 215) = 215

GCD(1, 215) = ( 1 x 215 ) / 215

= 1 / 215

= 1

So, Greatest Common Divisor of 669, 957, 308, 215 is 1
