Given numbers are 978, 472, 646, 829

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

Apply this formula for all numbers.

Step1:

LCM(978, 472) = 230808

GCD(978, 472) = ( 978 x 472 ) / 230808

= 978 / 472

= 978

Step2:

LCM(2, 646) = 646

GCD(2, 646) = ( 2 x 646 ) / 646

= 2 / 646

= 2

Step3:

LCM(2, 829) = 1658

GCD(2, 829) = ( 2 x 829 ) / 1658

= 2 / 829

= 2

So, Greatest Common Divisor of 978, 472, 646, 829 is 1
