Given numbers are 771, 564, 949, 840

The list of prime factors of all numbers are

Prime factors of 771 are 3 x 257

Prime factors of 564 are 2 x 2 x 3 x 47

Prime factors of 949 are 13 x 73

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

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

Given numbers are 771, 564, 949, 840

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

Apply this formula for all numbers.

Step1:

LCM(771, 564) = 144948

GCD(771, 564) = ( 771 x 564 ) / 144948

= 771 / 564

= 771

Step2:

LCM(3, 949) = 2847

GCD(3, 949) = ( 3 x 949 ) / 2847

= 3 / 949

= 3

Step3:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

So, Greatest Common Divisor of 771, 564, 949, 840 is 1
