Given numbers are 648, 278, 769, 403

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

Apply this formula for all numbers.

Step1:

LCM(648, 278) = 90072

GCD(648, 278) = ( 648 x 278 ) / 90072

= 648 / 278

= 648

Step2:

LCM(2, 769) = 1538

GCD(2, 769) = ( 2 x 769 ) / 1538

= 2 / 769

= 2

Step3:

LCM(1, 403) = 403

GCD(1, 403) = ( 1 x 403 ) / 403

= 1 / 403

= 1

So, Greatest Common Divisor of 648, 278, 769, 403 is 1
