Given numbers are 398, 236, 942, 355
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 236) = 46964
GCD(398, 236) = ( 398 x 236 ) / 46964
= 398 / 236
= 398
Step2:
LCM(2, 942) = 942
GCD(2, 942) = ( 2 x 942 ) / 942
= 2 / 942
= 2
Step3:
LCM(2, 355) = 710
GCD(2, 355) = ( 2 x 355 ) / 710
= 2 / 355
= 2
So, Greatest Common Divisor of 398, 236, 942, 355 is 1
