Given numbers are 628, 144, 141, 820

The list of prime factors of all numbers are

Prime factors of 628 are 2 x 2 x 157

Prime factors of 144 are 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 141 are 3 x 47

Prime factors of 820 are 2 x 2 x 5 x 41

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

Given numbers are 628, 144, 141, 820

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

Apply this formula for all numbers.

Step1:

LCM(628, 144) = 22608

GCD(628, 144) = ( 628 x 144 ) / 22608

= 628 / 144

= 628

Step2:

LCM(4, 141) = 564

GCD(4, 141) = ( 4 x 141 ) / 564

= 4 / 141

= 4

Step3:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 628, 144, 141, 820 is 1
