Given numbers are 686, 561, 635, 319
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 561) = 384846
GCD(686, 561) = ( 686 x 561 ) / 384846
= 686 / 561
= 686
Step2:
LCM(1, 635) = 635
GCD(1, 635) = ( 1 x 635 ) / 635
= 1 / 635
= 1
Step3:
LCM(1, 319) = 319
GCD(1, 319) = ( 1 x 319 ) / 319
= 1 / 319
= 1
So, Greatest Common Divisor of 686, 561, 635, 319 is 1
