Given numbers are 811, 578, 620, 272

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

Apply this formula for all numbers.

Step1:

LCM(811, 578) = 468758

GCD(811, 578) = ( 811 x 578 ) / 468758

= 811 / 578

= 811

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

Step3:

LCM(1, 272) = 272

GCD(1, 272) = ( 1 x 272 ) / 272

= 1 / 272

= 1

So, Greatest Common Divisor of 811, 578, 620, 272 is 1
