Given numbers are 829, 286, 978, 156

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

Apply this formula for all numbers.

Step1:

LCM(829, 286) = 237094

GCD(829, 286) = ( 829 x 286 ) / 237094

= 829 / 286

= 829

Step2:

LCM(1, 978) = 978

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

= 1 / 978

= 1

Step3:

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

= 1 / 156

= 1

So, Greatest Common Divisor of 829, 286, 978, 156 is 1
