Given numbers are 945, 770, 363, 220

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

Apply this formula for all numbers.

Step1:

LCM(945, 770) = 20790

GCD(945, 770) = ( 945 x 770 ) / 20790

= 945 / 770

= 945

Step2:

LCM(35, 363) = 12705

GCD(35, 363) = ( 35 x 363 ) / 12705

= 35 / 363

= 35

Step3:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

So, Greatest Common Divisor of 945, 770, 363, 220 is 1
