Given numbers are 728, 985, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(728, 985) = 717080
GCD(728, 985) = ( 728 x 985 ) / 717080
= 728 / 985
= 728
Step2:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
So, Greatest Common Divisor of 728, 985, 620 is 1
