Given numbers are 132, 123, 74, 261
The list of prime factors of all numbers are
Prime factors of 132 are 2 x 2 x 3 x 11
Prime factors of 123 are 3 x 41
Prime factors of 74 are 2 x 37
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 132, 123, 74, 261
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(132, 123) = 5412
GCD(132, 123) = ( 132 x 123 ) / 5412
= 132 / 123
= 132
Step2:
LCM(3, 74) = 222
GCD(3, 74) = ( 3 x 74 ) / 222
= 3 / 74
= 3
Step3:
LCM(1, 261) = 261
GCD(1, 261) = ( 1 x 261 ) / 261
= 1 / 261
= 1
So, Greatest Common Divisor of 132, 123, 74, 261 is 1
