Prime factors of 420 are 2 x 2 x 3 x 5 x 7
Prime factors of 623 are 7 x 89
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 213, 618, 420, 623
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(213, 618) = 43878
GCD(213, 618) = ( 213 x 618 ) / 43878
= 213 / 618
= 213
Step2:
LCM(3, 420) = 420
GCD(3, 420) = ( 3 x 420 ) / 420
= 3 / 420
= 3
Step3:
LCM(3, 623) = 1869
GCD(3, 623) = ( 3 x 623 ) / 1869
= 3 / 623
= 3
So, Greatest Common Divisor of 213, 618, 420, 623 is 1
