Given numbers are 969, 159, 279, 620

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

Apply this formula for all numbers.

Step1:

LCM(969, 159) = 51357

GCD(969, 159) = ( 969 x 159 ) / 51357

= 969 / 159

= 969

Step2:

LCM(3, 279) = 279

GCD(3, 279) = ( 3 x 279 ) / 279

= 3 / 279

= 3

Step3:

LCM(3, 620) = 1860

GCD(3, 620) = ( 3 x 620 ) / 1860

= 3 / 620

= 3

So, Greatest Common Divisor of 969, 159, 279, 620 is 1
