Given numbers are 398, 742, 242, 461
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 742) = 147658
GCD(398, 742) = ( 398 x 742 ) / 147658
= 398 / 742
= 398
Step2:
LCM(2, 242) = 242
GCD(2, 242) = ( 2 x 242 ) / 242
= 2 / 242
= 2
Step3:
LCM(2, 461) = 922
GCD(2, 461) = ( 2 x 461 ) / 922
= 2 / 461
= 2
So, Greatest Common Divisor of 398, 742, 242, 461 is 1
