Given numbers are 978, 297, 671, 478

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

Apply this formula for all numbers.

Step1:

LCM(978, 297) = 96822

GCD(978, 297) = ( 978 x 297 ) / 96822

= 978 / 297

= 978

Step2:

LCM(3, 671) = 2013

GCD(3, 671) = ( 3 x 671 ) / 2013

= 3 / 671

= 3

Step3:

LCM(1, 478) = 478

GCD(1, 478) = ( 1 x 478 ) / 478

= 1 / 478

= 1

So, Greatest Common Divisor of 978, 297, 671, 478 is 1
