Given numbers are 312, 969, 947, 745

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

Apply this formula for all numbers.

Step1:

LCM(312, 969) = 100776

GCD(312, 969) = ( 312 x 969 ) / 100776

= 312 / 969

= 312

Step2:

LCM(3, 947) = 2841

GCD(3, 947) = ( 3 x 947 ) / 2841

= 3 / 947

= 3

Step3:

LCM(1, 745) = 745

GCD(1, 745) = ( 1 x 745 ) / 745

= 1 / 745

= 1

So, Greatest Common Divisor of 312, 969, 947, 745 is 1
