Given numbers are 309, 822, 543, 715

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

Apply this formula for all numbers.

Step1:

LCM(309, 822) = 84666

GCD(309, 822) = ( 309 x 822 ) / 84666

= 309 / 822

= 309

Step2:

LCM(3, 543) = 543

GCD(3, 543) = ( 3 x 543 ) / 543

= 3 / 543

= 3

Step3:

LCM(3, 715) = 2145

GCD(3, 715) = ( 3 x 715 ) / 2145

= 3 / 715

= 3

So, Greatest Common Divisor of 309, 822, 543, 715 is 1
