Given numbers are 655, 863, 820, 281

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

Apply this formula for all numbers.

Step1:

LCM(655, 863) = 565265

GCD(655, 863) = ( 655 x 863 ) / 565265

= 655 / 863

= 655

Step2:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

Step3:

LCM(1, 281) = 281

GCD(1, 281) = ( 1 x 281 ) / 281

= 1 / 281

= 1

So, Greatest Common Divisor of 655, 863, 820, 281 is 1
