Given numbers are 667, 544, 656, 638

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

Apply this formula for all numbers.

Step1:

LCM(667, 544) = 362848

GCD(667, 544) = ( 667 x 544 ) / 362848

= 667 / 544

= 667

Step2:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 667, 544, 656, 638 is 1
