Given numbers are 128, 797, 661, 665

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

Apply this formula for all numbers.

Step1:

LCM(128, 797) = 102016

GCD(128, 797) = ( 128 x 797 ) / 102016

= 128 / 797

= 128

Step2:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

Step3:

LCM(1, 665) = 665

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

= 1 / 665

= 1

So, Greatest Common Divisor of 128, 797, 661, 665 is 1
