GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(386, 409) = 157874
GCD(386, 409) = ( 386 x 409 ) / 157874
= 386 / 409
= 386
Step2:
LCM(1, 988) = 988
GCD(1, 988) = ( 1 x 988 ) / 988
= 1 / 988
= 1
Step3:
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
= 1 / 438
= 1
So, Greatest Common Divisor of 386, 409, 988, 438 is 1
