The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 745, 868, 864, 857

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

Apply this formula for all numbers.

Step1:

LCM(745, 868) = 646660

GCD(745, 868) = ( 745 x 868 ) / 646660

= 745 / 868

= 745

Step2:

LCM(1, 864) = 864

GCD(1, 864) = ( 1 x 864 ) / 864

= 1 / 864

= 1

Step3:

LCM(1, 857) = 857

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

= 1 / 857

= 1

So, Greatest Common Divisor of 745, 868, 864, 857 is 1
