Given numbers are 649, 755, 380, 812

The list of prime factors of all numbers are

Prime factors of 649 are 11 x 59

Prime factors of 755 are 5 x 151

Prime factors of 380 are 2 x 2 x 5 x 19

Prime factors of 812 are 2 x 2 x 7 x 29

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

Given numbers are 649, 755, 380, 812

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

Apply this formula for all numbers.

Step1:

LCM(649, 755) = 489995

GCD(649, 755) = ( 649 x 755 ) / 489995

= 649 / 755

= 649

Step2:

LCM(1, 380) = 380

GCD(1, 380) = ( 1 x 380 ) / 380

= 1 / 380

= 1

Step3:

LCM(1, 812) = 812

GCD(1, 812) = ( 1 x 812 ) / 812

= 1 / 812

= 1

So, Greatest Common Divisor of 649, 755, 380, 812 is 1
