Given numbers are 445, 687, 52, 668

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

Apply this formula for all numbers.

Step1:

LCM(445, 687) = 305715

GCD(445, 687) = ( 445 x 687 ) / 305715

= 445 / 687

= 445

Step2:

LCM(1, 52) = 52

GCD(1, 52) = ( 1 x 52 ) / 52

= 1 / 52

= 1

Step3:

LCM(1, 668) = 668

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

= 1 / 668

= 1

So, Greatest Common Divisor of 445, 687, 52, 668 is 1
