Given numbers are 441, 231, 391, 685
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(441, 231) = 4851
GCD(441, 231) = ( 441 x 231 ) / 4851
= 441 / 231
= 441
Step2:
LCM(21, 391) = 8211
GCD(21, 391) = ( 21 x 391 ) / 8211
= 21 / 391
= 21
Step3:
LCM(1, 685) = 685
GCD(1, 685) = ( 1 x 685 ) / 685
= 1 / 685
= 1
So, Greatest Common Divisor of 441, 231, 391, 685 is 1
