Given numbers are 691, 217, 841, 694
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(691, 217) = 149947
GCD(691, 217) = ( 691 x 217 ) / 149947
= 691 / 217
= 691
Step2:
LCM(1, 841) = 841
GCD(1, 841) = ( 1 x 841 ) / 841
= 1 / 841
= 1
Step3:
LCM(1, 694) = 694
GCD(1, 694) = ( 1 x 694 ) / 694
= 1 / 694
= 1
So, Greatest Common Divisor of 691, 217, 841, 694 is 1
