Given numbers are 620, 509, 840, 740

The list of prime factors of all numbers are

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 509 are 509

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 740 are 2 x 2 x 5 x 37

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 620, 509, 840, 740

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

Apply this formula for all numbers.

Step1:

LCM(620, 509) = 315580

GCD(620, 509) = ( 620 x 509 ) / 315580

= 620 / 509

= 620

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 740) = 740

GCD(1, 740) = ( 1 x 740 ) / 740

= 1 / 740

= 1

So, Greatest Common Divisor of 620, 509, 840, 740 is 1
