GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(679, 138) = 93702
GCD(679, 138) = ( 679 x 138 ) / 93702
= 679 / 138
= 679
Step2:
LCM(1, 384) = 384
GCD(1, 384) = ( 1 x 384 ) / 384
= 1 / 384
= 1
Step3:
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
= 1 / 128
= 1
So, Greatest Common Divisor of 679, 138, 384, 128 is 1
