Given numbers are 436, 412, 656, 684

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

Apply this formula for all numbers.

Step1:

LCM(436, 412) = 44908

GCD(436, 412) = ( 436 x 412 ) / 44908

= 436 / 412

= 436

Step2:

LCM(4, 656) = 656

GCD(4, 656) = ( 4 x 656 ) / 656

= 4 / 656

= 4

Step3:

LCM(4, 684) = 684

GCD(4, 684) = ( 4 x 684 ) / 684

= 4 / 684

= 4

So, Greatest Common Divisor of 436, 412, 656, 684 is 4
