Given numbers are 289, 815, 721, 610
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(289, 815) = 235535
GCD(289, 815) = ( 289 x 815 ) / 235535
= 289 / 815
= 289
Step2:
LCM(1, 721) = 721
GCD(1, 721) = ( 1 x 721 ) / 721
= 1 / 721
= 1
Step3:
LCM(1, 610) = 610
GCD(1, 610) = ( 1 x 610 ) / 610
= 1 / 610
= 1
So, Greatest Common Divisor of 289, 815, 721, 610 is 1
