Given numbers are 819, 270, 128, 857

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

Apply this formula for all numbers.

Step1:

LCM(819, 270) = 24570

GCD(819, 270) = ( 819 x 270 ) / 24570

= 819 / 270

= 819

Step2:

LCM(9, 128) = 1152

GCD(9, 128) = ( 9 x 128 ) / 1152

= 9 / 128

= 9

Step3:

LCM(1, 857) = 857

GCD(1, 857) = ( 1 x 857 ) / 857

= 1 / 857

= 1

So, Greatest Common Divisor of 819, 270, 128, 857 is 1
