Given numbers are 291, 768, 64, 128

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

Apply this formula for all numbers.

Step1:

LCM(291, 768) = 74496

GCD(291, 768) = ( 291 x 768 ) / 74496

= 291 / 768

= 291

Step2:

LCM(3, 64) = 192

GCD(3, 64) = ( 3 x 64 ) / 192

= 3 / 64

= 3

Step3:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 291, 768, 64, 128 is 1
