Given numbers are 789, 749, 210, 662

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

Apply this formula for all numbers.

Step1:

LCM(789, 749) = 590961

GCD(789, 749) = ( 789 x 749 ) / 590961

= 789 / 749

= 789

Step2:

LCM(1, 210) = 210

GCD(1, 210) = ( 1 x 210 ) / 210

= 1 / 210

= 1

Step3:

LCM(1, 662) = 662

GCD(1, 662) = ( 1 x 662 ) / 662

= 1 / 662

= 1

So, Greatest Common Divisor of 789, 749, 210, 662 is 1
