Given numbers are 155, 375, 447, 891

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

Apply this formula for all numbers.

Step1:

LCM(155, 375) = 11625

GCD(155, 375) = ( 155 x 375 ) / 11625

= 155 / 375

= 155

Step2:

LCM(5, 447) = 2235

GCD(5, 447) = ( 5 x 447 ) / 2235

= 5 / 447

= 5

Step3:

LCM(1, 891) = 891

GCD(1, 891) = ( 1 x 891 ) / 891

= 1 / 891

= 1

So, Greatest Common Divisor of 155, 375, 447, 891 is 1
