Given numbers are 843, 291, 875, 978

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

Apply this formula for all numbers.

Step1:

LCM(843, 291) = 81771

GCD(843, 291) = ( 843 x 291 ) / 81771

= 843 / 291

= 843

Step2:

LCM(3, 875) = 2625

GCD(3, 875) = ( 3 x 875 ) / 2625

= 3 / 875

= 3

Step3:

LCM(1, 978) = 978

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

= 1 / 978

= 1

So, Greatest Common Divisor of 843, 291, 875, 978 is 1
