Given numbers are 901, 289, 891, 861

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

Apply this formula for all numbers.

Step1:

LCM(901, 289) = 15317

GCD(901, 289) = ( 901 x 289 ) / 15317

= 901 / 289

= 901

Step2:

LCM(17, 891) = 15147

GCD(17, 891) = ( 17 x 891 ) / 15147

= 17 / 891

= 17

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 901, 289, 891, 861 is 1
