Given numbers are 139, 479, 399, 415
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(139, 479) = 66581
GCD(139, 479) = ( 139 x 479 ) / 66581
= 139 / 479
= 139
Step2:
LCM(1, 399) = 399
GCD(1, 399) = ( 1 x 399 ) / 399
= 1 / 399
= 1
Step3:
LCM(1, 415) = 415
GCD(1, 415) = ( 1 x 415 ) / 415
= 1 / 415
= 1
So, Greatest Common Divisor of 139, 479, 399, 415 is 1
