Given numbers are 719, 815, 849, 420

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

Apply this formula for all numbers.

Step1:

LCM(719, 815) = 585985

GCD(719, 815) = ( 719 x 815 ) / 585985

= 719 / 815

= 719

Step2:

LCM(1, 849) = 849

GCD(1, 849) = ( 1 x 849 ) / 849

= 1 / 849

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 719, 815, 849, 420 is 1
