Given numbers are 684, 454, 257, 177
The list of prime factors of all numbers are
Prime factors of 684 are 2 x 2 x 3 x 3 x 19
Prime factors of 454 are 2 x 227
Prime factors of 257 are 257
Prime factors of 177 are 3 x 59
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 684, 454, 257, 177
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(684, 454) = 155268
GCD(684, 454) = ( 684 x 454 ) / 155268
= 684 / 454
= 684
Step2:
LCM(2, 257) = 514
GCD(2, 257) = ( 2 x 257 ) / 514
= 2 / 257
= 2
Step3:
LCM(1, 177) = 177
GCD(1, 177) = ( 1 x 177 ) / 177
= 1 / 177
= 1
So, Greatest Common Divisor of 684, 454, 257, 177 is 1
