Given numbers are 945, 470, 277, 245

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

Apply this formula for all numbers.

Step1:

LCM(945, 470) = 88830

GCD(945, 470) = ( 945 x 470 ) / 88830

= 945 / 470

= 945

Step2:

LCM(5, 277) = 1385

GCD(5, 277) = ( 5 x 277 ) / 1385

= 5 / 277

= 5

Step3:

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

= 1 / 245

= 1

So, Greatest Common Divisor of 945, 470, 277, 245 is 1
