Given numbers are 401, 742, 479, 138
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(401, 742) = 297542
GCD(401, 742) = ( 401 x 742 ) / 297542
= 401 / 742
= 401
Step2:
LCM(1, 479) = 479
GCD(1, 479) = ( 1 x 479 ) / 479
= 1 / 479
= 1
Step3:
LCM(1, 138) = 138
GCD(1, 138) = ( 1 x 138 ) / 138
= 1 / 138
= 1
So, Greatest Common Divisor of 401, 742, 479, 138 is 1
