The list of prime factors of all numbers are
Prime factors of 540 are 2 x 2 x 3 x 3 x 3 x 5
Prime factors of 110 are 2 x 5 x 11
Prime factors of 172 are 2 x 2 x 43
Prime factors of 391 are 17 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 540, 110, 172, 391
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(540, 110) = 5940
GCD(540, 110) = ( 540 x 110 ) / 5940
= 540 / 110
= 540
Step2:
LCM(10, 172) = 860
GCD(10, 172) = ( 10 x 172 ) / 860
= 10 / 172
= 10
Step3:
LCM(2, 391) = 782
GCD(2, 391) = ( 2 x 391 ) / 782
= 2 / 391
= 2
So, Greatest Common Divisor of 540, 110, 172, 391 is 1
