Given numbers are 381, 711, 609, 820

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

Apply this formula for all numbers.

Step1:

LCM(381, 711) = 90297

GCD(381, 711) = ( 381 x 711 ) / 90297

= 381 / 711

= 381

Step2:

LCM(3, 609) = 609

GCD(3, 609) = ( 3 x 609 ) / 609

= 3 / 609

= 3

Step3:

LCM(3, 820) = 2460

GCD(3, 820) = ( 3 x 820 ) / 2460

= 3 / 820

= 3

So, Greatest Common Divisor of 381, 711, 609, 820 is 1
