Given numbers are 642, 359, 622, 669

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

Apply this formula for all numbers.

Step1:

LCM(642, 359) = 230478

GCD(642, 359) = ( 642 x 359 ) / 230478

= 642 / 359

= 642

Step2:

LCM(1, 622) = 622

GCD(1, 622) = ( 1 x 622 ) / 622

= 1 / 622

= 1

Step3:

LCM(1, 669) = 669

GCD(1, 669) = ( 1 x 669 ) / 669

= 1 / 669

= 1

So, Greatest Common Divisor of 642, 359, 622, 669 is 1
