Given numbers are 686, 591, 698, 222
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 591) = 405426
GCD(686, 591) = ( 686 x 591 ) / 405426
= 686 / 591
= 686
Step2:
LCM(1, 698) = 698
GCD(1, 698) = ( 1 x 698 ) / 698
= 1 / 698
= 1
Step3:
LCM(1, 222) = 222
GCD(1, 222) = ( 1 x 222 ) / 222
= 1 / 222
= 1
So, Greatest Common Divisor of 686, 591, 698, 222 is 1
