The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 445, 751, 390, 864
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(445, 751) = 334195
GCD(445, 751) = ( 445 x 751 ) / 334195
= 445 / 751
= 445
Step2:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
Step3:
LCM(1, 864) = 864
GCD(1, 864) = ( 1 x 864 ) / 864
= 1 / 864
= 1
So, Greatest Common Divisor of 445, 751, 390, 864 is 1
