Given numbers are 693, 207, 385, 687
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(693, 207) = 15939
GCD(693, 207) = ( 693 x 207 ) / 15939
= 693 / 207
= 693
Step2:
LCM(9, 385) = 3465
GCD(9, 385) = ( 9 x 385 ) / 3465
= 9 / 385
= 9
Step3:
LCM(1, 687) = 687
GCD(1, 687) = ( 1 x 687 ) / 687
= 1 / 687
= 1
So, Greatest Common Divisor of 693, 207, 385, 687 is 1
