Given numbers are 854, 655, 486, 644

The list of prime factors of all numbers are

Prime factors of 854 are 2 x 7 x 61

Prime factors of 655 are 5 x 131

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

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 854, 655, 486, 644

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

Apply this formula for all numbers.

Step1:

LCM(854, 655) = 559370

GCD(854, 655) = ( 854 x 655 ) / 559370

= 854 / 655

= 854

Step2:

LCM(1, 486) = 486

GCD(1, 486) = ( 1 x 486 ) / 486

= 1 / 486

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 854, 655, 486, 644 is 1
