Given numbers are 686, 561, 282, 777
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, 282) = 282
GCD(1, 282) = ( 1 x 282 ) / 282
= 1 / 282
= 1
Step3:
LCM(1, 777) = 777
GCD(1, 777) = ( 1 x 777 ) / 777
= 1 / 777
= 1
So, Greatest Common Divisor of 686, 561, 282, 777 is 1
