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

Apply this formula for all numbers.

Step1:

LCM(642, 909) = 194526

GCD(642, 909) = ( 642 x 909 ) / 194526

= 642 / 909

= 642

Step2:

LCM(3, 544) = 1632

GCD(3, 544) = ( 3 x 544 ) / 1632

= 3 / 544

= 3

Step3:

LCM(1, 266) = 266

GCD(1, 266) = ( 1 x 266 ) / 266

= 1 / 266

= 1

So, Greatest Common Divisor of 642, 909, 544, 266 is 1
