Given numbers are 619, 620, 840, 809

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

Apply this formula for all numbers.

Step1:

LCM(619, 620) = 383780

GCD(619, 620) = ( 619 x 620 ) / 383780

= 619 / 620

= 619

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

= 1 / 809

= 1

So, Greatest Common Divisor of 619, 620, 840, 809 is 1
