Given numbers are 161, 162, 978

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

Apply this formula for all numbers.

Step1:

LCM(161, 162) = 26082

GCD(161, 162) = ( 161 x 162 ) / 26082

= 161 / 162

= 161

Step2:

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

= 1 / 978

= 1

So, Greatest Common Divisor of 161, 162, 978 is 1
