Given numbers are 691, 871, 211, 572
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(691, 871) = 601861
GCD(691, 871) = ( 691 x 871 ) / 601861
= 691 / 871
= 691
Step2:
LCM(1, 211) = 211
GCD(1, 211) = ( 1 x 211 ) / 211
= 1 / 211
= 1
Step3:
LCM(1, 572) = 572
GCD(1, 572) = ( 1 x 572 ) / 572
= 1 / 572
= 1
So, Greatest Common Divisor of 691, 871, 211, 572 is 1
