Given numbers are 646, 603, 668, 110

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

Apply this formula for all numbers.

Step1:

LCM(646, 603) = 389538

GCD(646, 603) = ( 646 x 603 ) / 389538

= 646 / 603

= 646

Step2:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

Step3:

LCM(1, 110) = 110

GCD(1, 110) = ( 1 x 110 ) / 110

= 1 / 110

= 1

So, Greatest Common Divisor of 646, 603, 668, 110 is 1
