Given numbers are 603, 497, 156, 821

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

Apply this formula for all numbers.

Step1:

LCM(603, 497) = 299691

GCD(603, 497) = ( 603 x 497 ) / 299691

= 603 / 497

= 603

Step2:

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

= 1 / 156

= 1

Step3:

LCM(1, 821) = 821

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

= 1 / 821

= 1

So, Greatest Common Divisor of 603, 497, 156, 821 is 1
