Given numbers are 479, 620, 607, 398
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(479, 620) = 296980
GCD(479, 620) = ( 479 x 620 ) / 296980
= 479 / 620
= 479
Step2:
LCM(1, 607) = 607
GCD(1, 607) = ( 1 x 607 ) / 607
= 1 / 607
= 1
Step3:
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
= 1 / 398
= 1
So, Greatest Common Divisor of 479, 620, 607, 398 is 1
