Given numbers are 644, 268, 434, 461

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

Apply this formula for all numbers.

Step1:

LCM(644, 268) = 43148

GCD(644, 268) = ( 644 x 268 ) / 43148

= 644 / 268

= 644

Step2:

LCM(4, 434) = 868

GCD(4, 434) = ( 4 x 434 ) / 868

= 4 / 434

= 4

Step3:

LCM(2, 461) = 922

GCD(2, 461) = ( 2 x 461 ) / 922

= 2 / 461

= 2

So, Greatest Common Divisor of 644, 268, 434, 461 is 1
