Given numbers are 648, 881, 778, 556

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

Apply this formula for all numbers.

Step1:

LCM(648, 881) = 570888

GCD(648, 881) = ( 648 x 881 ) / 570888

= 648 / 881

= 648

Step2:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

Step3:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

So, Greatest Common Divisor of 648, 881, 778, 556 is 1
