Given numbers are 669, 647, 940, 212

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

Apply this formula for all numbers.

Step1:

LCM(669, 647) = 432843

GCD(669, 647) = ( 669 x 647 ) / 432843

= 669 / 647

= 669

Step2:

LCM(1, 940) = 940

GCD(1, 940) = ( 1 x 940 ) / 940

= 1 / 940

= 1

Step3:

LCM(1, 212) = 212

GCD(1, 212) = ( 1 x 212 ) / 212

= 1 / 212

= 1

So, Greatest Common Divisor of 669, 647, 940, 212 is 1
