Given numbers are 528, 644, 355, 678

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 644 are 2 x 2 x 7 x 23

Prime factors of 355 are 5 x 71

Prime factors of 678 are 2 x 3 x 113

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

Given numbers are 528, 644, 355, 678

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

Apply this formula for all numbers.

Step1:

LCM(528, 644) = 85008

GCD(528, 644) = ( 528 x 644 ) / 85008

= 528 / 644

= 528

Step2:

LCM(4, 355) = 1420

GCD(4, 355) = ( 4 x 355 ) / 1420

= 4 / 355

= 4

Step3:

LCM(1, 678) = 678

GCD(1, 678) = ( 1 x 678 ) / 678

= 1 / 678

= 1

So, Greatest Common Divisor of 528, 644, 355, 678 is 1
