The list of prime factors of all numbers are
Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3
Prime factors of 705 are 3 x 5 x 47
Prime factors of 155 are 5 x 31
Prime factors of 441 are 3 x 3 x 7 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 432, 705, 155, 441
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(432, 705) = 101520
GCD(432, 705) = ( 432 x 705 ) / 101520
= 432 / 705
= 432
Step2:
LCM(3, 155) = 465
GCD(3, 155) = ( 3 x 155 ) / 465
= 3 / 155
= 3
Step3:
LCM(1, 441) = 441
GCD(1, 441) = ( 1 x 441 ) / 441
= 1 / 441
= 1
So, Greatest Common Divisor of 432, 705, 155, 441 is 1
