Given numbers are 209, 380, 824, 615

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

Apply this formula for all numbers.

Step1:

LCM(209, 380) = 4180

GCD(209, 380) = ( 209 x 380 ) / 4180

= 209 / 380

= 209

Step2:

LCM(19, 824) = 15656

GCD(19, 824) = ( 19 x 824 ) / 15656

= 19 / 824

= 19

Step3:

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

= 1 / 615

= 1

So, Greatest Common Divisor of 209, 380, 824, 615 is 1
