Given numbers are 891, 783, 308, 154

The list of prime factors of all numbers are

Prime factors of 891 are 3 x 3 x 3 x 3 x 11

Prime factors of 783 are 3 x 3 x 3 x 29

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 154 are 2 x 7 x 11

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

Given numbers are 891, 783, 308, 154

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

Apply this formula for all numbers.

Step1:

LCM(891, 783) = 25839

GCD(891, 783) = ( 891 x 783 ) / 25839

= 891 / 783

= 891

Step2:

LCM(27, 308) = 8316

GCD(27, 308) = ( 27 x 308 ) / 8316

= 27 / 308

= 27

Step3:

LCM(1, 154) = 154

GCD(1, 154) = ( 1 x 154 ) / 154

= 1 / 154

= 1

So, Greatest Common Divisor of 891, 783, 308, 154 is 1
