GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(421, 698) = 293858
GCD(421, 698) = ( 421 x 698 ) / 293858
= 421 / 698
= 421
Step2:
LCM(1, 294) = 294
GCD(1, 294) = ( 1 x 294 ) / 294
= 1 / 294
= 1
Step3:
LCM(1, 409) = 409
GCD(1, 409) = ( 1 x 409 ) / 409
= 1 / 409
= 1
So, Greatest Common Divisor of 421, 698, 294, 409 is 1
