Given numbers are 921, 225, 325, 685

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

Apply this formula for all numbers.

Step1:

LCM(921, 225) = 69075

GCD(921, 225) = ( 921 x 225 ) / 69075

= 921 / 225

= 921

Step2:

LCM(3, 325) = 975

GCD(3, 325) = ( 3 x 325 ) / 975

= 3 / 325

= 3

Step3:

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

= 1 / 685

= 1

So, Greatest Common Divisor of 921, 225, 325, 685 is 1
