Given numbers are 620, 198, 154, 670

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

Apply this formula for all numbers.

Step1:

LCM(620, 198) = 61380

GCD(620, 198) = ( 620 x 198 ) / 61380

= 620 / 198

= 620

Step2:

LCM(2, 154) = 154

GCD(2, 154) = ( 2 x 154 ) / 154

= 2 / 154

= 2

Step3:

LCM(2, 670) = 670

GCD(2, 670) = ( 2 x 670 ) / 670

= 2 / 670

= 2

So, Greatest Common Divisor of 620, 198, 154, 670 is 2
