Given numbers are 189, 644, 694, 670

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

Apply this formula for all numbers.

Step1:

LCM(189, 644) = 17388

GCD(189, 644) = ( 189 x 644 ) / 17388

= 189 / 644

= 189

Step2:

LCM(7, 694) = 4858

GCD(7, 694) = ( 7 x 694 ) / 4858

= 7 / 694

= 7

Step3:

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

= 1 / 670

= 1

So, Greatest Common Divisor of 189, 644, 694, 670 is 1
