Given numbers are 555, 669, 438, 970

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

Apply this formula for all numbers.

Step1:

LCM(555, 669) = 123765

GCD(555, 669) = ( 555 x 669 ) / 123765

= 555 / 669

= 555

Step2:

LCM(3, 438) = 438

GCD(3, 438) = ( 3 x 438 ) / 438

= 3 / 438

= 3

Step3:

LCM(3, 970) = 2910

GCD(3, 970) = ( 3 x 970 ) / 2910

= 3 / 970

= 3

So, Greatest Common Divisor of 555, 669, 438, 970 is 1
