Given numbers are 620, 974, 189, 207

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

Apply this formula for all numbers.

Step1:

LCM(620, 974) = 301940

GCD(620, 974) = ( 620 x 974 ) / 301940

= 620 / 974

= 620

Step2:

LCM(2, 189) = 378

GCD(2, 189) = ( 2 x 189 ) / 378

= 2 / 189

= 2

Step3:

LCM(1, 207) = 207

GCD(1, 207) = ( 1 x 207 ) / 207

= 1 / 207

= 1

So, Greatest Common Divisor of 620, 974, 189, 207 is 1
