Given numbers are 417, 786, 777, 689

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

Apply this formula for all numbers.

Step1:

LCM(417, 786) = 109254

GCD(417, 786) = ( 417 x 786 ) / 109254

= 417 / 786

= 417

Step2:

LCM(3, 777) = 777

GCD(3, 777) = ( 3 x 777 ) / 777

= 3 / 777

= 3

Step3:

LCM(3, 689) = 2067

GCD(3, 689) = ( 3 x 689 ) / 2067

= 3 / 689

= 3

So, Greatest Common Divisor of 417, 786, 777, 689 is 1
