Given numbers are 849, 441, 786, 644

The list of prime factors of all numbers are

Prime factors of 849 are 3 x 283

Prime factors of 441 are 3 x 3 x 7 x 7

Prime factors of 786 are 2 x 3 x 131

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 849, 441, 786, 644

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

Apply this formula for all numbers.

Step1:

LCM(849, 441) = 124803

GCD(849, 441) = ( 849 x 441 ) / 124803

= 849 / 441

= 849

Step2:

LCM(3, 786) = 786

GCD(3, 786) = ( 3 x 786 ) / 786

= 3 / 786

= 3

Step3:

LCM(3, 644) = 1932

GCD(3, 644) = ( 3 x 644 ) / 1932

= 3 / 644

= 3

So, Greatest Common Divisor of 849, 441, 786, 644 is 1
