Given numbers are 665, 987, 149, 497

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

Apply this formula for all numbers.

Step1:

LCM(665, 987) = 93765

GCD(665, 987) = ( 665 x 987 ) / 93765

= 665 / 987

= 665

Step2:

LCM(7, 149) = 1043

GCD(7, 149) = ( 7 x 149 ) / 1043

= 7 / 149

= 7

Step3:

LCM(1, 497) = 497

GCD(1, 497) = ( 1 x 497 ) / 497

= 1 / 497

= 1

So, Greatest Common Divisor of 665, 987, 149, 497 is 1
