Given numbers are 563, 603, 821, 786

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

Apply this formula for all numbers.

Step1:

LCM(563, 603) = 339489

GCD(563, 603) = ( 563 x 603 ) / 339489

= 563 / 603

= 563

Step2:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

Step3:

LCM(1, 786) = 786

GCD(1, 786) = ( 1 x 786 ) / 786

= 1 / 786

= 1

So, Greatest Common Divisor of 563, 603, 821, 786 is 1
