Given numbers are 685, 725, 621, 311
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 725) = 99325
GCD(685, 725) = ( 685 x 725 ) / 99325
= 685 / 725
= 685
Step2:
LCM(5, 621) = 3105
GCD(5, 621) = ( 5 x 621 ) / 3105
= 5 / 621
= 5
Step3:
LCM(1, 311) = 311
GCD(1, 311) = ( 1 x 311 ) / 311
= 1 / 311
= 1
So, Greatest Common Divisor of 685, 725, 621, 311 is 1
