GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 784) = 83888
GCD(428, 784) = ( 428 x 784 ) / 83888
= 428 / 784
= 428
Step2:
LCM(4, 597) = 2388
GCD(4, 597) = ( 4 x 597 ) / 2388
= 4 / 597
= 4
Step3:
LCM(1, 409) = 409
GCD(1, 409) = ( 1 x 409 ) / 409
= 1 / 409
= 1
So, Greatest Common Divisor of 428, 784, 597, 409 is 1
