Given numbers are 154, 749, 769, 768

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

Apply this formula for all numbers.

Step1:

LCM(154, 749) = 16478

GCD(154, 749) = ( 154 x 749 ) / 16478

= 154 / 749

= 154

Step2:

LCM(7, 769) = 5383

GCD(7, 769) = ( 7 x 769 ) / 5383

= 7 / 769

= 7

Step3:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

So, Greatest Common Divisor of 154, 749, 769, 768 is 1
