Given numbers are 402, 685, 185, 556
The list of prime factors of all numbers are
Prime factors of 402 are 2 x 3 x 67
Prime factors of 685 are 5 x 137
Prime factors of 185 are 5 x 37
Prime factors of 556 are 2 x 2 x 139
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 402, 685, 185, 556
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(402, 685) = 275370
GCD(402, 685) = ( 402 x 685 ) / 275370
= 402 / 685
= 402
Step2:
LCM(1, 185) = 185
GCD(1, 185) = ( 1 x 185 ) / 185
= 1 / 185
= 1
Step3:
LCM(1, 556) = 556
GCD(1, 556) = ( 1 x 556 ) / 556
= 1 / 556
= 1
So, Greatest Common Divisor of 402, 685, 185, 556 is 1
