Given numbers are 398, 206, 576, 755
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 206) = 40994
GCD(398, 206) = ( 398 x 206 ) / 40994
= 398 / 206
= 398
Step2:
LCM(2, 576) = 576
GCD(2, 576) = ( 2 x 576 ) / 576
= 2 / 576
= 2
Step3:
LCM(2, 755) = 1510
GCD(2, 755) = ( 2 x 755 ) / 1510
= 2 / 755
= 2
So, Greatest Common Divisor of 398, 206, 576, 755 is 1
