Given numbers are 231, 520, 693, 847
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(231, 520) = 120120
GCD(231, 520) = ( 231 x 520 ) / 120120
= 231 / 520
= 231
Step2:
LCM(1, 693) = 693
GCD(1, 693) = ( 1 x 693 ) / 693
= 1 / 693
= 1
Step3:
LCM(1, 847) = 847
GCD(1, 847) = ( 1 x 847 ) / 847
= 1 / 847
= 1
So, Greatest Common Divisor of 231, 520, 693, 847 is 1
