Given numbers are 128, 982, 245, 563

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

Apply this formula for all numbers.

Step1:

LCM(128, 982) = 62848

GCD(128, 982) = ( 128 x 982 ) / 62848

= 128 / 982

= 128

Step2:

LCM(2, 245) = 490

GCD(2, 245) = ( 2 x 245 ) / 490

= 2 / 245

= 2

Step3:

LCM(1, 563) = 563

GCD(1, 563) = ( 1 x 563 ) / 563

= 1 / 563

= 1

So, Greatest Common Divisor of 128, 982, 245, 563 is 1
