Given numbers are 649, 440, 654, 528

The list of prime factors of all numbers are

Prime factors of 649 are 11 x 59

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

Prime factors of 654 are 2 x 3 x 109

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

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

Given numbers are 649, 440, 654, 528

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

Apply this formula for all numbers.

Step1:

LCM(649, 440) = 25960

GCD(649, 440) = ( 649 x 440 ) / 25960

= 649 / 440

= 649

Step2:

LCM(11, 654) = 7194

GCD(11, 654) = ( 11 x 654 ) / 7194

= 11 / 654

= 11

Step3:

LCM(1, 528) = 528

GCD(1, 528) = ( 1 x 528 ) / 528

= 1 / 528

= 1

So, Greatest Common Divisor of 649, 440, 654, 528 is 1
