Given numbers are 834, 257, 145, 261
The list of prime factors of all numbers are
Prime factors of 834 are 2 x 3 x 139
Prime factors of 257 are 257
Prime factors of 145 are 5 x 29
Prime factors of 261 are 3 x 3 x 29
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 834, 257, 145, 261
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(834, 257) = 214338
GCD(834, 257) = ( 834 x 257 ) / 214338
= 834 / 257
= 834
Step2:
LCM(1, 145) = 145
GCD(1, 145) = ( 1 x 145 ) / 145
= 1 / 145
= 1
Step3:
LCM(1, 261) = 261
GCD(1, 261) = ( 1 x 261 ) / 261
= 1 / 261
= 1
So, Greatest Common Divisor of 834, 257, 145, 261 is 1
