Given numbers are 528, 614, 820, 643

The list of prime factors of all numbers are

Prime factors of 528 are 2 x 2 x 2 x 2 x 3 x 11

Prime factors of 614 are 2 x 307

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 643 are 643

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

Given numbers are 528, 614, 820, 643

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

Apply this formula for all numbers.

Step1:

LCM(528, 614) = 162096

GCD(528, 614) = ( 528 x 614 ) / 162096

= 528 / 614

= 528

Step2:

LCM(2, 820) = 820

GCD(2, 820) = ( 2 x 820 ) / 820

= 2 / 820

= 2

Step3:

LCM(2, 643) = 1286

GCD(2, 643) = ( 2 x 643 ) / 1286

= 2 / 643

= 2

So, Greatest Common Divisor of 528, 614, 820, 643 is 1
