Given numbers are 251, 550, 445, 126
The list of prime factors of all numbers are
Prime factors of 251 are 251
Prime factors of 550 are 2 x 5 x 5 x 11
Prime factors of 445 are 5 x 89
Prime factors of 126 are 2 x 3 x 3 x 7
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 251, 550, 445, 126
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(251, 550) = 138050
GCD(251, 550) = ( 251 x 550 ) / 138050
= 251 / 550
= 251
Step2:
LCM(1, 445) = 445
GCD(1, 445) = ( 1 x 445 ) / 445
= 1 / 445
= 1
Step3:
LCM(1, 126) = 126
GCD(1, 126) = ( 1 x 126 ) / 126
= 1 / 126
= 1
So, Greatest Common Divisor of 251, 550, 445, 126 is 1
