Given numbers are 690, 196, 257, 325
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 196) = 67620
GCD(690, 196) = ( 690 x 196 ) / 67620
= 690 / 196
= 690
Step2:
LCM(2, 257) = 514
GCD(2, 257) = ( 2 x 257 ) / 514
= 2 / 257
= 2
Step3:
LCM(1, 325) = 325
GCD(1, 325) = ( 1 x 325 ) / 325
= 1 / 325
= 1
So, Greatest Common Divisor of 690, 196, 257, 325 is 1
