Given numbers are 909, 207, 774, 770

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

Apply this formula for all numbers.

Step1:

LCM(909, 207) = 20907

GCD(909, 207) = ( 909 x 207 ) / 20907

= 909 / 207

= 909

Step2:

LCM(9, 774) = 774

GCD(9, 774) = ( 9 x 774 ) / 774

= 9 / 774

= 9

Step3:

LCM(9, 770) = 6930

GCD(9, 770) = ( 9 x 770 ) / 6930

= 9 / 770

= 9

So, Greatest Common Divisor of 909, 207, 774, 770 is 1
