Given numbers are 649, 640, 747, 773

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

Apply this formula for all numbers.

Step1:

LCM(649, 640) = 415360

GCD(649, 640) = ( 649 x 640 ) / 415360

= 649 / 640

= 649

Step2:

LCM(1, 747) = 747

GCD(1, 747) = ( 1 x 747 ) / 747

= 1 / 747

= 1

Step3:

LCM(1, 773) = 773

GCD(1, 773) = ( 1 x 773 ) / 773

= 1 / 773

= 1

So, Greatest Common Divisor of 649, 640, 747, 773 is 1
