Given numbers are 666, 721, 586, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(666, 721) = 480186
GCD(666, 721) = ( 666 x 721 ) / 480186
= 666 / 721
= 666
Step2:
LCM(1, 586) = 586
GCD(1, 586) = ( 1 x 586 ) / 586
= 1 / 586
= 1
Step3:
LCM(1, 257) = 257
GCD(1, 257) = ( 1 x 257 ) / 257
= 1 / 257
= 1
So, Greatest Common Divisor of 666, 721, 586, 257 is 1
