Given numbers are 688, 628, 623, 354

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

Apply this formula for all numbers.

Step1:

LCM(688, 628) = 108016

GCD(688, 628) = ( 688 x 628 ) / 108016

= 688 / 628

= 688

Step2:

LCM(4, 623) = 2492

GCD(4, 623) = ( 4 x 623 ) / 2492

= 4 / 623

= 4

Step3:

LCM(1, 354) = 354

GCD(1, 354) = ( 1 x 354 ) / 354

= 1 / 354

= 1

So, Greatest Common Divisor of 688, 628, 623, 354 is 1
