Given numbers are 325, 215, 823, 690

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

Apply this formula for all numbers.

Step1:

LCM(325, 215) = 13975

GCD(325, 215) = ( 325 x 215 ) / 13975

= 325 / 215

= 325

Step2:

LCM(5, 823) = 4115

GCD(5, 823) = ( 5 x 823 ) / 4115

= 5 / 823

= 5

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 325, 215, 823, 690 is 1
