Given numbers are 770, 906, 978, 163

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

Apply this formula for all numbers.

Step1:

LCM(770, 906) = 348810

GCD(770, 906) = ( 770 x 906 ) / 348810

= 770 / 906

= 770

Step2:

LCM(2, 978) = 978

GCD(2, 978) = ( 2 x 978 ) / 978

= 2 / 978

= 2

Step3:

LCM(2, 163) = 326

GCD(2, 163) = ( 2 x 163 ) / 326

= 2 / 163

= 2

So, Greatest Common Divisor of 770, 906, 978, 163 is 1
