Given numbers are 858, 781, 275, 942

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

Apply this formula for all numbers.

Step1:

LCM(858, 781) = 60918

GCD(858, 781) = ( 858 x 781 ) / 60918

= 858 / 781

= 858

Step2:

LCM(11, 275) = 275

GCD(11, 275) = ( 11 x 275 ) / 275

= 11 / 275

= 11

Step3:

LCM(11, 942) = 10362

GCD(11, 942) = ( 11 x 942 ) / 10362

= 11 / 942

= 11

So, Greatest Common Divisor of 858, 781, 275, 942 is 1
