Given numbers are 289, 386, 720, 436
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(289, 386) = 111554
GCD(289, 386) = ( 289 x 386 ) / 111554
= 289 / 386
= 289
Step2:
LCM(1, 720) = 720
GCD(1, 720) = ( 1 x 720 ) / 720
= 1 / 720
= 1
Step3:
LCM(1, 436) = 436
GCD(1, 436) = ( 1 x 436 ) / 436
= 1 / 436
= 1
So, Greatest Common Divisor of 289, 386, 720, 436 is 1
