Given numbers are 945, 345, 528, 685

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

Apply this formula for all numbers.

Step1:

LCM(945, 345) = 21735

GCD(945, 345) = ( 945 x 345 ) / 21735

= 945 / 345

= 945

Step2:

LCM(15, 528) = 2640

GCD(15, 528) = ( 15 x 528 ) / 2640

= 15 / 528

= 15

Step3:

LCM(3, 685) = 2055

GCD(3, 685) = ( 3 x 685 ) / 2055

= 3 / 685

= 3

So, Greatest Common Divisor of 945, 345, 528, 685 is 1
