Given numbers are 530, 815, 353, 878

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

Apply this formula for all numbers.

Step1:

LCM(530, 815) = 86390

GCD(530, 815) = ( 530 x 815 ) / 86390

= 530 / 815

= 530

Step2:

LCM(5, 353) = 1765

GCD(5, 353) = ( 5 x 353 ) / 1765

= 5 / 353

= 5

Step3:

LCM(1, 878) = 878

GCD(1, 878) = ( 1 x 878 ) / 878

= 1 / 878

= 1

So, Greatest Common Divisor of 530, 815, 353, 878 is 1
