Given numbers are 321, 391, 437, 810
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(321, 391) = 125511
GCD(321, 391) = ( 321 x 391 ) / 125511
= 321 / 391
= 321
Step2:
LCM(1, 437) = 437
GCD(1, 437) = ( 1 x 437 ) / 437
= 1 / 437
= 1
Step3:
LCM(1, 810) = 810
GCD(1, 810) = ( 1 x 810 ) / 810
= 1 / 810
= 1
So, Greatest Common Divisor of 321, 391, 437, 810 is 1
