Given numbers are 649, 451, 778, 408

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

Apply this formula for all numbers.

Step1:

LCM(649, 451) = 26609

GCD(649, 451) = ( 649 x 451 ) / 26609

= 649 / 451

= 649

Step2:

LCM(11, 778) = 8558

GCD(11, 778) = ( 11 x 778 ) / 8558

= 11 / 778

= 11

Step3:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

So, Greatest Common Divisor of 649, 451, 778, 408 is 1
