Given numbers are 621, 945, 855, 719

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

Apply this formula for all numbers.

Step1:

LCM(621, 945) = 21735

GCD(621, 945) = ( 621 x 945 ) / 21735

= 621 / 945

= 621

Step2:

LCM(27, 855) = 2565

GCD(27, 855) = ( 27 x 855 ) / 2565

= 27 / 855

= 27

Step3:

LCM(9, 719) = 6471

GCD(9, 719) = ( 9 x 719 ) / 6471

= 9 / 719

= 9

So, Greatest Common Divisor of 621, 945, 855, 719 is 1
