Given numbers are 923, 390, 969, 646

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

Apply this formula for all numbers.

Step1:

LCM(923, 390) = 27690

GCD(923, 390) = ( 923 x 390 ) / 27690

= 923 / 390

= 923

Step2:

LCM(13, 969) = 12597

GCD(13, 969) = ( 13 x 969 ) / 12597

= 13 / 969

= 13

Step3:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 923, 390, 969, 646 is 1
