Given numbers are 665, 889, 969, 811

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

Apply this formula for all numbers.

Step1:

LCM(665, 889) = 84455

GCD(665, 889) = ( 665 x 889 ) / 84455

= 665 / 889

= 665

Step2:

LCM(7, 969) = 6783

GCD(7, 969) = ( 7 x 969 ) / 6783

= 7 / 969

= 7

Step3:

LCM(1, 811) = 811

GCD(1, 811) = ( 1 x 811 ) / 811

= 1 / 811

= 1

So, Greatest Common Divisor of 665, 889, 969, 811 is 1
