Given numbers are 815, 140, 866, 525

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 140 are 2 x 2 x 5 x 7

Prime factors of 866 are 2 x 433

Prime factors of 525 are 3 x 5 x 5 x 7

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

Given numbers are 815, 140, 866, 525

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

Apply this formula for all numbers.

Step1:

LCM(815, 140) = 22820

GCD(815, 140) = ( 815 x 140 ) / 22820

= 815 / 140

= 815

Step2:

LCM(5, 866) = 4330

GCD(5, 866) = ( 5 x 866 ) / 4330

= 5 / 866

= 5

Step3:

LCM(1, 525) = 525

GCD(1, 525) = ( 1 x 525 ) / 525

= 1 / 525

= 1

So, Greatest Common Divisor of 815, 140, 866, 525 is 1
