Given numbers are 815, 309, 957, 954

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

Apply this formula for all numbers.

Step1:

LCM(815, 309) = 251835

GCD(815, 309) = ( 815 x 309 ) / 251835

= 815 / 309

= 815

Step2:

LCM(1, 957) = 957

GCD(1, 957) = ( 1 x 957 ) / 957

= 1 / 957

= 1

Step3:

LCM(1, 954) = 954

GCD(1, 954) = ( 1 x 954 ) / 954

= 1 / 954

= 1

So, Greatest Common Divisor of 815, 309, 957, 954 is 1
