Given numbers are 572, 247, 23, 642

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

Apply this formula for all numbers.

Step1:

LCM(572, 247) = 10868

GCD(572, 247) = ( 572 x 247 ) / 10868

= 572 / 247

= 572

Step2:

LCM(13, 23) = 299

GCD(13, 23) = ( 13 x 23 ) / 299

= 13 / 23

= 13

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 572, 247, 23, 642 is 1
