Given numbers are 665, 722, 987, 165

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

Apply this formula for all numbers.

Step1:

LCM(665, 722) = 25270

GCD(665, 722) = ( 665 x 722 ) / 25270

= 665 / 722

= 665

Step2:

LCM(19, 987) = 18753

GCD(19, 987) = ( 19 x 987 ) / 18753

= 19 / 987

= 19

Step3:

LCM(1, 165) = 165

GCD(1, 165) = ( 1 x 165 ) / 165

= 1 / 165

= 1

So, Greatest Common Divisor of 665, 722, 987, 165 is 1
