Given numbers are 969, 742, 400, 665

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

Apply this formula for all numbers.

Step1:

LCM(969, 742) = 718998

GCD(969, 742) = ( 969 x 742 ) / 718998

= 969 / 742

= 969

Step2:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

Step3:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 969, 742, 400, 665 is 1
