Given numbers are 978, 411, 840, 435

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

Apply this formula for all numbers.

Step1:

LCM(978, 411) = 133986

GCD(978, 411) = ( 978 x 411 ) / 133986

= 978 / 411

= 978

Step2:

LCM(3, 840) = 840

GCD(3, 840) = ( 3 x 840 ) / 840

= 3 / 840

= 3

Step3:

LCM(3, 435) = 435

GCD(3, 435) = ( 3 x 435 ) / 435

= 3 / 435

= 3

So, Greatest Common Divisor of 978, 411, 840, 435 is 3
