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 120 are 2 x 2 x 2 x 3 x 5
Prime factors of 159 are 3 x 53
Prime factors of 511 are 7 x 73
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 728, 120, 159, 511
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(728, 120) = 10920
GCD(728, 120) = ( 728 x 120 ) / 10920
= 728 / 120
= 728
Step2:
LCM(8, 159) = 1272
GCD(8, 159) = ( 8 x 159 ) / 1272
= 8 / 159
= 8
Step3:
LCM(1, 511) = 511
GCD(1, 511) = ( 1 x 511 ) / 511
= 1 / 511
= 1
So, Greatest Common Divisor of 728, 120, 159, 511 is 1
