Given numbers are 768, 639, 227, 649

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

Apply this formula for all numbers.

Step1:

LCM(768, 639) = 163584

GCD(768, 639) = ( 768 x 639 ) / 163584

= 768 / 639

= 768

Step2:

LCM(3, 227) = 681

GCD(3, 227) = ( 3 x 227 ) / 681

= 3 / 227

= 3

Step3:

LCM(1, 649) = 649

GCD(1, 649) = ( 1 x 649 ) / 649

= 1 / 649

= 1

So, Greatest Common Divisor of 768, 639, 227, 649 is 1
