Given numbers are 648, 729, 985, 761

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

Apply this formula for all numbers.

Step1:

LCM(648, 729) = 5832

GCD(648, 729) = ( 648 x 729 ) / 5832

= 648 / 729

= 648

Step2:

LCM(81, 985) = 79785

GCD(81, 985) = ( 81 x 985 ) / 79785

= 81 / 985

= 81

Step3:

LCM(1, 761) = 761

GCD(1, 761) = ( 1 x 761 ) / 761

= 1 / 761

= 1

So, Greatest Common Divisor of 648, 729, 985, 761 is 1
