GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(810, 394) = 159570
GCD(810, 394) = ( 810 x 394 ) / 159570
= 810 / 394
= 810
Step2:
LCM(2, 486) = 486
GCD(2, 486) = ( 2 x 486 ) / 486
= 2 / 486
= 2
Step3:
LCM(2, 860) = 860
GCD(2, 860) = ( 2 x 860 ) / 860
= 2 / 860
= 2
So, Greatest Common Divisor of 810, 394, 486, 860 is 2
