Given numbers are 157, 128, 290, 891

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

Apply this formula for all numbers.

Step1:

LCM(157, 128) = 20096

GCD(157, 128) = ( 157 x 128 ) / 20096

= 157 / 128

= 157

Step2:

LCM(1, 290) = 290

GCD(1, 290) = ( 1 x 290 ) / 290

= 1 / 290

= 1

Step3:

LCM(1, 891) = 891

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

= 1 / 891

= 1

So, Greatest Common Divisor of 157, 128, 290, 891 is 1
