Given numbers are 857, 921, 145, 338

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

Apply this formula for all numbers.

Step1:

LCM(857, 921) = 789297

GCD(857, 921) = ( 857 x 921 ) / 789297

= 857 / 921

= 857

Step2:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

Step3:

LCM(1, 338) = 338

GCD(1, 338) = ( 1 x 338 ) / 338

= 1 / 338

= 1

So, Greatest Common Divisor of 857, 921, 145, 338 is 1
