Given numbers are 689, 455, 955, 497
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(689, 455) = 24115
GCD(689, 455) = ( 689 x 455 ) / 24115
= 689 / 455
= 689
Step2:
LCM(13, 955) = 12415
GCD(13, 955) = ( 13 x 955 ) / 12415
= 13 / 955
= 13
Step3:
LCM(1, 497) = 497
GCD(1, 497) = ( 1 x 497 ) / 497
= 1 / 497
= 1
So, Greatest Common Divisor of 689, 455, 955, 497 is 1
