Given numbers are 620, 678, 402, 375

The list of prime factors of all numbers are

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

Prime factors of 678 are 2 x 3 x 113

Prime factors of 402 are 2 x 3 x 67

Prime factors of 375 are 3 x 5 x 5 x 5

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

Given numbers are 620, 678, 402, 375

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

Apply this formula for all numbers.

Step1:

LCM(620, 678) = 210180

GCD(620, 678) = ( 620 x 678 ) / 210180

= 620 / 678

= 620

Step2:

LCM(2, 402) = 402

GCD(2, 402) = ( 2 x 402 ) / 402

= 2 / 402

= 2

Step3:

LCM(2, 375) = 750

GCD(2, 375) = ( 2 x 375 ) / 750

= 2 / 375

= 2

So, Greatest Common Divisor of 620, 678, 402, 375 is 1
