Given numbers are 744, 420, 601, 620
The list of prime factors of all numbers are
Prime factors of 744 are 2 x 2 x 2 x 3 x 31
Prime factors of 420 are 2 x 2 x 3 x 5 x 7
Prime factors of 601 are 601
Prime factors of 620 are 2 x 2 x 5 x 31
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 744, 420, 601, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(744, 420) = 26040
GCD(744, 420) = ( 744 x 420 ) / 26040
= 744 / 420
= 744
Step2:
LCM(12, 601) = 7212
GCD(12, 601) = ( 12 x 601 ) / 7212
= 12 / 601
= 12
Step3:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
So, Greatest Common Divisor of 744, 420, 601, 620 is 1
