Given numbers are 276, 657, 149, 780

The list of prime factors of all numbers are

Prime factors of 276 are 2 x 2 x 3 x 23

Prime factors of 657 are 3 x 3 x 73

Prime factors of 149 are 149

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

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

Given numbers are 276, 657, 149, 780

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

Apply this formula for all numbers.

Step1:

LCM(276, 657) = 60444

GCD(276, 657) = ( 276 x 657 ) / 60444

= 276 / 657

= 276

Step2:

LCM(3, 149) = 447

GCD(3, 149) = ( 3 x 149 ) / 447

= 3 / 149

= 3

Step3:

LCM(1, 780) = 780

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

= 1 / 780

= 1

So, Greatest Common Divisor of 276, 657, 149, 780 is 1
