Given numbers are 639, 426, 945, 641

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

Apply this formula for all numbers.

Step1:

LCM(639, 426) = 1278

GCD(639, 426) = ( 639 x 426 ) / 1278

= 639 / 426

= 639

Step2:

LCM(213, 945) = 67095

GCD(213, 945) = ( 213 x 945 ) / 67095

= 213 / 945

= 213

Step3:

LCM(3, 641) = 1923

GCD(3, 641) = ( 3 x 641 ) / 1923

= 3 / 641

= 3

So, Greatest Common Divisor of 639, 426, 945, 641 is 1
