Given numbers are 505, 970, 811, 985

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

Apply this formula for all numbers.

Step1:

LCM(505, 970) = 97970

GCD(505, 970) = ( 505 x 970 ) / 97970

= 505 / 970

= 505

Step2:

LCM(5, 811) = 4055

GCD(5, 811) = ( 5 x 811 ) / 4055

= 5 / 811

= 5

Step3:

LCM(1, 985) = 985

GCD(1, 985) = ( 1 x 985 ) / 985

= 1 / 985

= 1

So, Greatest Common Divisor of 505, 970, 811, 985 is 1
