GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 424) = 145432
GCD(686, 424) = ( 686 x 424 ) / 145432
= 686 / 424
= 686
Step2:
LCM(2, 121) = 242
GCD(2, 121) = ( 2 x 121 ) / 242
= 2 / 121
= 2
Step3:
LCM(1, 814) = 814
GCD(1, 814) = ( 1 x 814 ) / 814
= 1 / 814
= 1
So, Greatest Common Divisor of 686, 424, 121, 814 is 1
