Given numbers are 562, 678, 688, 905

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

Apply this formula for all numbers.

Step1:

LCM(562, 678) = 190518

GCD(562, 678) = ( 562 x 678 ) / 190518

= 562 / 678

= 562

Step2:

LCM(2, 688) = 688

GCD(2, 688) = ( 2 x 688 ) / 688

= 2 / 688

= 2

Step3:

LCM(2, 905) = 1810

GCD(2, 905) = ( 2 x 905 ) / 1810

= 2 / 905

= 2

So, Greatest Common Divisor of 562, 678, 688, 905 is 1
