Given numbers are 398, 420, 629, 481
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(398, 420) = 83580
GCD(398, 420) = ( 398 x 420 ) / 83580
= 398 / 420
= 398
Step2:
LCM(2, 629) = 1258
GCD(2, 629) = ( 2 x 629 ) / 1258
= 2 / 629
= 2
Step3:
LCM(1, 481) = 481
GCD(1, 481) = ( 1 x 481 ) / 481
= 1 / 481
= 1
So, Greatest Common Divisor of 398, 420, 629, 481 is 1
