Given numbers are 439, 530, 438, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(439, 530) = 232670
GCD(439, 530) = ( 439 x 530 ) / 232670
= 439 / 530
= 439
Step2:
LCM(1, 438) = 438
GCD(1, 438) = ( 1 x 438 ) / 438
= 1 / 438
= 1
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 439, 530, 438, 646 is 1
