Given numbers are 153, 115, 686, 517
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(153, 115) = 17595
GCD(153, 115) = ( 153 x 115 ) / 17595
= 153 / 115
= 153
Step2:
LCM(1, 686) = 686
GCD(1, 686) = ( 1 x 686 ) / 686
= 1 / 686
= 1
Step3:
LCM(1, 517) = 517
GCD(1, 517) = ( 1 x 517 ) / 517
= 1 / 517
= 1
So, Greatest Common Divisor of 153, 115, 686, 517 is 1
