Given numbers are 665, 931, 457, 138

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(665, 931) = 4655

GCD(665, 931) = ( 665 x 931 ) / 4655

= 665 / 931

= 665

Step2:

LCM(133, 457) = 60781

GCD(133, 457) = ( 133 x 457 ) / 60781

= 133 / 457

= 133

Step3:

LCM(1, 138) = 138

GCD(1, 138) = ( 1 x 138 ) / 138

= 1 / 138

= 1

So, Greatest Common Divisor of 665, 931, 457, 138 is 1
