Given numbers are 665, 171, 491, 355

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

Apply this formula for all numbers.

Step1:

LCM(665, 171) = 5985

GCD(665, 171) = ( 665 x 171 ) / 5985

= 665 / 171

= 665

Step2:

LCM(19, 491) = 9329

GCD(19, 491) = ( 19 x 491 ) / 9329

= 19 / 491

= 19

Step3:

LCM(1, 355) = 355

GCD(1, 355) = ( 1 x 355 ) / 355

= 1 / 355

= 1

So, Greatest Common Divisor of 665, 171, 491, 355 is 1
