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

Apply this formula for all numbers.

Step1:

LCM(847, 238) = 28798

GCD(847, 238) = ( 847 x 238 ) / 28798

= 847 / 238

= 847

Step2:

LCM(7, 429) = 3003

GCD(7, 429) = ( 7 x 429 ) / 3003

= 7 / 429

= 7

Step3:

LCM(1, 978) = 978

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

= 1 / 978

= 1

So, Greatest Common Divisor of 847, 238, 429, 978 is 1
