Given numbers are 276, 690, 815, 275

The list of prime factors of all numbers are

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

Prime factors of 690 are 2 x 3 x 5 x 23

Prime factors of 815 are 5 x 163

Prime factors of 275 are 5 x 5 x 11

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

Given numbers are 276, 690, 815, 275

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

Apply this formula for all numbers.

Step1:

LCM(276, 690) = 1380

GCD(276, 690) = ( 276 x 690 ) / 1380

= 276 / 690

= 276

Step2:

LCM(138, 815) = 112470

GCD(138, 815) = ( 138 x 815 ) / 112470

= 138 / 815

= 138

Step3:

LCM(1, 275) = 275

GCD(1, 275) = ( 1 x 275 ) / 275

= 1 / 275

= 1

So, Greatest Common Divisor of 276, 690, 815, 275 is 1
