Given numbers are 811, 728, 620, 683
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(811, 728) = 590408
GCD(811, 728) = ( 811 x 728 ) / 590408
= 811 / 728
= 811
Step2:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
Step3:
LCM(1, 683) = 683
GCD(1, 683) = ( 1 x 683 ) / 683
= 1 / 683
= 1
So, Greatest Common Divisor of 811, 728, 620, 683 is 1
