Given numbers are 427, 978, 207, 844

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

Apply this formula for all numbers.

Step1:

LCM(427, 978) = 417606

GCD(427, 978) = ( 427 x 978 ) / 417606

= 427 / 978

= 427

Step2:

LCM(1, 207) = 207

GCD(1, 207) = ( 1 x 207 ) / 207

= 1 / 207

= 1

Step3:

LCM(1, 844) = 844

GCD(1, 844) = ( 1 x 844 ) / 844

= 1 / 844

= 1

So, Greatest Common Divisor of 427, 978, 207, 844 is 1
