Given numbers are 155, 525, 774, 981

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

Apply this formula for all numbers.

Step1:

LCM(155, 525) = 16275

GCD(155, 525) = ( 155 x 525 ) / 16275

= 155 / 525

= 155

Step2:

LCM(5, 774) = 3870

GCD(5, 774) = ( 5 x 774 ) / 3870

= 5 / 774

= 5

Step3:

LCM(1, 981) = 981

GCD(1, 981) = ( 1 x 981 ) / 981

= 1 / 981

= 1

So, Greatest Common Divisor of 155, 525, 774, 981 is 1
