Given numbers are 643, 350, 711, 254
The list of prime factors of all numbers are
Prime factors of 643 are 643
Prime factors of 350 are 2 x 5 x 5 x 7
Prime factors of 711 are 3 x 3 x 79
Prime factors of 254 are 2 x 127
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 643, 350, 711, 254
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 350) = 225050
GCD(643, 350) = ( 643 x 350 ) / 225050
= 643 / 350
= 643
Step2:
LCM(1, 711) = 711
GCD(1, 711) = ( 1 x 711 ) / 711
= 1 / 711
= 1
Step3:
LCM(1, 254) = 254
GCD(1, 254) = ( 1 x 254 ) / 254
= 1 / 254
= 1
So, Greatest Common Divisor of 643, 350, 711, 254 is 1
