Given numbers are 945, 477, 155, 785

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

Apply this formula for all numbers.

Step1:

LCM(945, 477) = 50085

GCD(945, 477) = ( 945 x 477 ) / 50085

= 945 / 477

= 945

Step2:

LCM(9, 155) = 1395

GCD(9, 155) = ( 9 x 155 ) / 1395

= 9 / 155

= 9

Step3:

LCM(1, 785) = 785

GCD(1, 785) = ( 1 x 785 ) / 785

= 1 / 785

= 1

So, Greatest Common Divisor of 945, 477, 155, 785 is 1
