Given numbers are 434, 280, 821, 687

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

Apply this formula for all numbers.

Step1:

LCM(434, 280) = 8680

GCD(434, 280) = ( 434 x 280 ) / 8680

= 434 / 280

= 434

Step2:

LCM(14, 821) = 11494

GCD(14, 821) = ( 14 x 821 ) / 11494

= 14 / 821

= 14

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 434, 280, 821, 687 is 1
