Given numbers are 560, 895, 815, 243

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

Apply this formula for all numbers.

Step1:

LCM(560, 895) = 100240

GCD(560, 895) = ( 560 x 895 ) / 100240

= 560 / 895

= 560

Step2:

LCM(5, 815) = 815

GCD(5, 815) = ( 5 x 815 ) / 815

= 5 / 815

= 5

Step3:

LCM(5, 243) = 1215

GCD(5, 243) = ( 5 x 243 ) / 1215

= 5 / 243

= 5

So, Greatest Common Divisor of 560, 895, 815, 243 is 1
