Given numbers are 209, 115, 141, 970

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

Apply this formula for all numbers.

Step1:

LCM(209, 115) = 24035

GCD(209, 115) = ( 209 x 115 ) / 24035

= 209 / 115

= 209

Step2:

LCM(1, 141) = 141

GCD(1, 141) = ( 1 x 141 ) / 141

= 1 / 141

= 1

Step3:

LCM(1, 970) = 970

GCD(1, 970) = ( 1 x 970 ) / 970

= 1 / 970

= 1

So, Greatest Common Divisor of 209, 115, 141, 970 is 1
