Given numbers are 851, 685, 906, 321
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(851, 685) = 582935
GCD(851, 685) = ( 851 x 685 ) / 582935
= 851 / 685
= 851
Step2:
LCM(1, 906) = 906
GCD(1, 906) = ( 1 x 906 ) / 906
= 1 / 906
= 1
Step3:
LCM(1, 321) = 321
GCD(1, 321) = ( 1 x 321 ) / 321
= 1 / 321
= 1
So, Greatest Common Divisor of 851, 685, 906, 321 is 1
