Given numbers are 620, 978, 467, 253

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

Apply this formula for all numbers.

Step1:

LCM(620, 978) = 303180

GCD(620, 978) = ( 620 x 978 ) / 303180

= 620 / 978

= 620

Step2:

LCM(2, 467) = 934

GCD(2, 467) = ( 2 x 467 ) / 934

= 2 / 467

= 2

Step3:

LCM(1, 253) = 253

GCD(1, 253) = ( 1 x 253 ) / 253

= 1 / 253

= 1

So, Greatest Common Divisor of 620, 978, 467, 253 is 1
