Given numbers are 686, 188, 621, 331
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 188) = 64484
GCD(686, 188) = ( 686 x 188 ) / 64484
= 686 / 188
= 686
Step2:
LCM(2, 621) = 1242
GCD(2, 621) = ( 2 x 621 ) / 1242
= 2 / 621
= 2
Step3:
LCM(1, 331) = 331
GCD(1, 331) = ( 1 x 331 ) / 331
= 1 / 331
= 1
So, Greatest Common Divisor of 686, 188, 621, 331 is 1
