Given numbers are 978, 162, 457

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

Apply this formula for all numbers.

Step1:

LCM(978, 162) = 26406

GCD(978, 162) = ( 978 x 162 ) / 26406

= 978 / 162

= 978

Step2:

LCM(6, 457) = 2742

GCD(6, 457) = ( 6 x 457 ) / 2742

= 6 / 457

= 6

So, Greatest Common Divisor of 978, 162, 457 is 1
