Given numbers are 682, 861, 409, 664
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(682, 861) = 587202
GCD(682, 861) = ( 682 x 861 ) / 587202
= 682 / 861
= 682
Step2:
LCM(1, 409) = 409
GCD(1, 409) = ( 1 x 409 ) / 409
= 1 / 409
= 1
Step3:
LCM(1, 664) = 664
GCD(1, 664) = ( 1 x 664 ) / 664
= 1 / 664
= 1
So, Greatest Common Divisor of 682, 861, 409, 664 is 1
