Given numbers are 890, 645, 729, 682

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

Apply this formula for all numbers.

Step1:

LCM(890, 645) = 114810

GCD(890, 645) = ( 890 x 645 ) / 114810

= 890 / 645

= 890

Step2:

LCM(5, 729) = 3645

GCD(5, 729) = ( 5 x 729 ) / 3645

= 5 / 729

= 5

Step3:

LCM(1, 682) = 682

GCD(1, 682) = ( 1 x 682 ) / 682

= 1 / 682

= 1

So, Greatest Common Divisor of 890, 645, 729, 682 is 1
