Given numbers are 686, 440, 186, 417
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 440) = 150920
GCD(686, 440) = ( 686 x 440 ) / 150920
= 686 / 440
= 686
Step2:
LCM(2, 186) = 186
GCD(2, 186) = ( 2 x 186 ) / 186
= 2 / 186
= 2
Step3:
LCM(2, 417) = 834
GCD(2, 417) = ( 2 x 417 ) / 834
= 2 / 417
= 2
So, Greatest Common Divisor of 686, 440, 186, 417 is 1
