Given numbers are 620, 655, 645, 372

The list of prime factors of all numbers are

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

Prime factors of 655 are 5 x 131

Prime factors of 645 are 3 x 5 x 43

Prime factors of 372 are 2 x 2 x 3 x 31

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

Given numbers are 620, 655, 645, 372

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

Apply this formula for all numbers.

Step1:

LCM(620, 655) = 81220

GCD(620, 655) = ( 620 x 655 ) / 81220

= 620 / 655

= 620

Step2:

LCM(5, 645) = 645

GCD(5, 645) = ( 5 x 645 ) / 645

= 5 / 645

= 5

Step3:

LCM(5, 372) = 1860

GCD(5, 372) = ( 5 x 372 ) / 1860

= 5 / 372

= 5

So, Greatest Common Divisor of 620, 655, 645, 372 is 1
