Given numbers are 643, 856, 265, 914

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

Apply this formula for all numbers.

Step1:

LCM(643, 856) = 550408

GCD(643, 856) = ( 643 x 856 ) / 550408

= 643 / 856

= 643

Step2:

LCM(1, 265) = 265

GCD(1, 265) = ( 1 x 265 ) / 265

= 1 / 265

= 1

Step3:

LCM(1, 914) = 914

GCD(1, 914) = ( 1 x 914 ) / 914

= 1 / 914

= 1

So, Greatest Common Divisor of 643, 856, 265, 914 is 1
