Given numbers are 620, 806, 65, 243

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

Apply this formula for all numbers.

Step1:

LCM(620, 806) = 8060

GCD(620, 806) = ( 620 x 806 ) / 8060

= 620 / 806

= 620

Step2:

LCM(62, 65) = 4030

GCD(62, 65) = ( 62 x 65 ) / 4030

= 62 / 65

= 62

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 620, 806, 65, 243 is 1
