Given numbers are 550, 581, 644, 554
The list of prime factors of all numbers are
Prime factors of 550 are 2 x 5 x 5 x 11
Prime factors of 581 are 7 x 83
Prime factors of 644 are 2 x 2 x 7 x 23
Prime factors of 554 are 2 x 277
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 550, 581, 644, 554
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(550, 581) = 319550
GCD(550, 581) = ( 550 x 581 ) / 319550
= 550 / 581
= 550
Step2:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
Step3:
LCM(1, 554) = 554
GCD(1, 554) = ( 1 x 554 ) / 554
= 1 / 554
= 1
So, Greatest Common Divisor of 550, 581, 644, 554 is 1
