Given numbers are 161, 809, 780, 907

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

Apply this formula for all numbers.

Step1:

LCM(161, 809) = 130249

GCD(161, 809) = ( 161 x 809 ) / 130249

= 161 / 809

= 161

Step2:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

Step3:

LCM(1, 907) = 907

GCD(1, 907) = ( 1 x 907 ) / 907

= 1 / 907

= 1

So, Greatest Common Divisor of 161, 809, 780, 907 is 1
