Given numbers are 770, 155, 449, 979

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

Apply this formula for all numbers.

Step1:

LCM(770, 155) = 23870

GCD(770, 155) = ( 770 x 155 ) / 23870

= 770 / 155

= 770

Step2:

LCM(5, 449) = 2245

GCD(5, 449) = ( 5 x 449 ) / 2245

= 5 / 449

= 5

Step3:

LCM(1, 979) = 979

GCD(1, 979) = ( 1 x 979 ) / 979

= 1 / 979

= 1

So, Greatest Common Divisor of 770, 155, 449, 979 is 1
