Given numbers are 215, 835, 858, 242

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

Apply this formula for all numbers.

Step1:

LCM(215, 835) = 35905

GCD(215, 835) = ( 215 x 835 ) / 35905

= 215 / 835

= 215

Step2:

LCM(5, 858) = 4290

GCD(5, 858) = ( 5 x 858 ) / 4290

= 5 / 858

= 5

Step3:

LCM(1, 242) = 242

GCD(1, 242) = ( 1 x 242 ) / 242

= 1 / 242

= 1

So, Greatest Common Divisor of 215, 835, 858, 242 is 1
