Given numbers are 147, 390, 571, 969

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

Apply this formula for all numbers.

Step1:

LCM(147, 390) = 19110

GCD(147, 390) = ( 147 x 390 ) / 19110

= 147 / 390

= 147

Step2:

LCM(3, 571) = 1713

GCD(3, 571) = ( 3 x 571 ) / 1713

= 3 / 571

= 3

Step3:

LCM(1, 969) = 969

GCD(1, 969) = ( 1 x 969 ) / 969

= 1 / 969

= 1

So, Greatest Common Divisor of 147, 390, 571, 969 is 1
