Given numbers are 649, 785, 780, 187

The list of prime factors of all numbers are

Prime factors of 649 are 11 x 59

Prime factors of 785 are 5 x 157

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 187 are 11 x 17

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

Given numbers are 649, 785, 780, 187

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

Apply this formula for all numbers.

Step1:

LCM(649, 785) = 509465

GCD(649, 785) = ( 649 x 785 ) / 509465

= 649 / 785

= 649

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 187) = 187

GCD(1, 187) = ( 1 x 187 ) / 187

= 1 / 187

= 1

So, Greatest Common Divisor of 649, 785, 780, 187 is 1
