Given numbers are 642, 564, 282, 689

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

Apply this formula for all numbers.

Step1:

LCM(642, 564) = 60348

GCD(642, 564) = ( 642 x 564 ) / 60348

= 642 / 564

= 642

Step2:

LCM(6, 282) = 282

GCD(6, 282) = ( 6 x 282 ) / 282

= 6 / 282

= 6

Step3:

LCM(6, 689) = 4134

GCD(6, 689) = ( 6 x 689 ) / 4134

= 6 / 689

= 6

So, Greatest Common Divisor of 642, 564, 282, 689 is 1
