Given numbers are 207, 822, 565, 861

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

Apply this formula for all numbers.

Step1:

LCM(207, 822) = 56718

GCD(207, 822) = ( 207 x 822 ) / 56718

= 207 / 822

= 207

Step2:

LCM(3, 565) = 1695

GCD(3, 565) = ( 3 x 565 ) / 1695

= 3 / 565

= 3

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 207, 822, 565, 861 is 1
