Given numbers are 161, 805, 678, 975

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

Apply this formula for all numbers.

Step1:

LCM(161, 805) = 805

GCD(161, 805) = ( 161 x 805 ) / 805

= 161 / 805

= 161

Step2:

LCM(161, 678) = 109158

GCD(161, 678) = ( 161 x 678 ) / 109158

= 161 / 678

= 161

Step3:

LCM(1, 975) = 975

GCD(1, 975) = ( 1 x 975 ) / 975

= 1 / 975

= 1

So, Greatest Common Divisor of 161, 805, 678, 975 is 1
