Given numbers are 728, 836, 643, 141

The list of prime factors of all numbers are

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

Prime factors of 836 are 2 x 2 x 11 x 19

Prime factors of 643 are 643

Prime factors of 141 are 3 x 47

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

Given numbers are 728, 836, 643, 141

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

Apply this formula for all numbers.

Step1:

LCM(728, 836) = 152152

GCD(728, 836) = ( 728 x 836 ) / 152152

= 728 / 836

= 728

Step2:

LCM(4, 643) = 2572

GCD(4, 643) = ( 4 x 643 ) / 2572

= 4 / 643

= 4

Step3:

LCM(1, 141) = 141

GCD(1, 141) = ( 1 x 141 ) / 141

= 1 / 141

= 1

So, Greatest Common Divisor of 728, 836, 643, 141 is 1
