Given numbers are 826, 644, 900, 691

The list of prime factors of all numbers are

Prime factors of 826 are 2 x 7 x 59

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 900 are 2 x 2 x 3 x 3 x 5 x 5

Prime factors of 691 are 691

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

Given numbers are 826, 644, 900, 691

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

Apply this formula for all numbers.

Step1:

LCM(826, 644) = 37996

GCD(826, 644) = ( 826 x 644 ) / 37996

= 826 / 644

= 826

Step2:

LCM(14, 900) = 6300

GCD(14, 900) = ( 14 x 900 ) / 6300

= 14 / 900

= 14

Step3:

LCM(2, 691) = 1382

GCD(2, 691) = ( 2 x 691 ) / 1382

= 2 / 691

= 2

So, Greatest Common Divisor of 826, 644, 900, 691 is 1
