Given numbers are 820, 473, 453, 863

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

Apply this formula for all numbers.

Step1:

LCM(820, 473) = 387860

GCD(820, 473) = ( 820 x 473 ) / 387860

= 820 / 473

= 820

Step2:

LCM(1, 453) = 453

GCD(1, 453) = ( 1 x 453 ) / 453

= 1 / 453

= 1

Step3:

LCM(1, 863) = 863

GCD(1, 863) = ( 1 x 863 ) / 863

= 1 / 863

= 1

So, Greatest Common Divisor of 820, 473, 453, 863 is 1
