GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 194) = 38606
GCD(398, 194) = ( 398 x 194 ) / 38606
= 398 / 194
= 398
Step2:
LCM(2, 528) = 528
GCD(2, 528) = ( 2 x 528 ) / 528
= 2 / 528
= 2
Step3:
LCM(2, 434) = 434
GCD(2, 434) = ( 2 x 434 ) / 434
= 2 / 434
= 2
So, Greatest Common Divisor of 398, 194, 528, 434 is 2
