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 506 are 2 x 11 x 23
Prime factors of 478 are 2 x 239
Prime factors of 621 are 3 x 3 x 3 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 432, 506, 478, 621
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(432, 506) = 109296
GCD(432, 506) = ( 432 x 506 ) / 109296
= 432 / 506
= 432
Step2:
LCM(2, 478) = 478
GCD(2, 478) = ( 2 x 478 ) / 478
= 2 / 478
= 2
Step3:
LCM(2, 621) = 1242
GCD(2, 621) = ( 2 x 621 ) / 1242
= 2 / 621
= 2
So, Greatest Common Divisor of 432, 506, 478, 621 is 1
