Given numbers are 654, 278, 486, 891

The list of prime factors of all numbers are

Prime factors of 654 are 2 x 3 x 109

Prime factors of 278 are 2 x 139

Prime factors of 486 are 2 x 3 x 3 x 3 x 3 x 3

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

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

Given numbers are 654, 278, 486, 891

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

Apply this formula for all numbers.

Step1:

LCM(654, 278) = 90906

GCD(654, 278) = ( 654 x 278 ) / 90906

= 654 / 278

= 654

Step2:

LCM(2, 486) = 486

GCD(2, 486) = ( 2 x 486 ) / 486

= 2 / 486

= 2

Step3:

LCM(2, 891) = 1782

GCD(2, 891) = ( 2 x 891 ) / 1782

= 2 / 891

= 2

So, Greatest Common Divisor of 654, 278, 486, 891 is 1
