Given numbers are 645, 841, 520, 762

The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 841 are 29 x 29

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 762 are 2 x 3 x 127

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

Given numbers are 645, 841, 520, 762

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

Apply this formula for all numbers.

Step1:

LCM(645, 841) = 542445

GCD(645, 841) = ( 645 x 841 ) / 542445

= 645 / 841

= 645

Step2:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

Step3:

LCM(1, 762) = 762

GCD(1, 762) = ( 1 x 762 ) / 762

= 1 / 762

= 1

So, Greatest Common Divisor of 645, 841, 520, 762 is 1
