Given numbers are 161, 780, 978, 212

The list of prime factors of all numbers are

Prime factors of 161 are 7 x 23

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 978 are 2 x 3 x 163

Prime factors of 212 are 2 x 2 x 53

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 161, 780, 978, 212

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

Apply this formula for all numbers.

Step1:

LCM(161, 780) = 125580

GCD(161, 780) = ( 161 x 780 ) / 125580

= 161 / 780

= 161

Step2:

LCM(1, 978) = 978

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

= 1 / 978

= 1

Step3:

LCM(1, 212) = 212

GCD(1, 212) = ( 1 x 212 ) / 212

= 1 / 212

= 1

So, Greatest Common Divisor of 161, 780, 978, 212 is 1
