Given numbers are 438, 810, 315, 194
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 810) = 59130
GCD(438, 810) = ( 438 x 810 ) / 59130
= 438 / 810
= 438
Step2:
LCM(6, 315) = 630
GCD(6, 315) = ( 6 x 315 ) / 630
= 6 / 315
= 6
Step3:
LCM(3, 194) = 582
GCD(3, 194) = ( 3 x 194 ) / 582
= 3 / 194
= 3
So, Greatest Common Divisor of 438, 810, 315, 194 is 1
